The European SI metric system does not have a unit of measurement for volume called the gallon. This is one of the inconveniences of using it. Another difficulty is that it is impossible to say definitively how many liters are in a gallon. There are groups of countries with the English gallon; in other countries the American gallon is used. Most often, this volume measure is used for liquids; less often, it is used to measure bulk substances.

It is believed to be approximately 3.785 liters. Although this unit is an English system, it is only 0.833 of an English gallon. It's hard to say why Americans use their own measurement standard. It was originally equal to the volume of 8 feet of wheat, so a pint is 0.125 (1/8) of a gallon. The amount of alcohol in these two countries is also determined differently. An American proof gallon is 1.89 liters, an English one is 2.594 liters. Bulk solids such as grain, corn and others are measured the same in both of these countries - 4.405 liters is the measure of interest to us.

This is the name of this English unit of measurement. It is believed that there are 4.546 liters in a gallon. This means that 100 gal = 454.6 liters. Ireland, Canada and other English-speaking countries are accustomed to this volume measure; Liberia, Colombia, Nicaragua prefer the American version. The English system of measures has many other metric equivalents for the unit of volume. For example, their well-known 1 barrel is equal to approximately 37 gallons (about 166 liters), but there is also a “barrel” for beer, its volume is equal to 36 imperial gallons (164 liters). A barrel for unrefined (crude) oil has its own measurement, even smaller, 34 gal.

What should Russians and car travelers do?

The cost of gasoline in different countries of the world depends on many conditions. Primarily on the cost of oil. In Iran, Venezuela, and Turkmenistan, where it is mined, gasoline is much cheaper. Although there is no single price in these countries, since oil is of different quality, denser, less saturated. How much does gasoline cost in Europe, America, African and Asian countries? How many liters are in one gallon? Units of measurement for commodities vary so much, even within the same country, that it is difficult to remember the conversion factor. Motorists around the world, however, are very sociable people. Based on their impressions, checks, and some official documents, the following table was compiled.

The price of AI95 gasoline in some countries of the world in terms of rubles in the summer of 2013

If you don’t know how many liters are in a gallon, then the approximate cost of gasoline can be compared with your financial capabilities.

While the table was being printed, prices may have changed. In order to accurately say how many liters are in a gallon and how much a gallon of gasoline costs, it is necessary to find out the coefficient upon arrival in the country and convert it into rubles. However, even in this case one cannot hope for perfect accuracy; all equivalents are rounded. There is a tendency that this metric system will eventually become a thing of the past, replaced by the International SI System, and therefore we will no longer have to deal with the question of how many liters are in a gallon.

General information

Volume is the space occupied by a substance or object. Volume can also refer to the free space inside a container. Volume is a three-dimensional quantity, unlike, for example, length, which is two-dimensional. Therefore, the volume of flat or two-dimensional objects is zero.

Volume units

Cubic meter

The SI unit of volume is the cubic meter. The standard definition of one cubic meter is the volume of a cube with edges one meter long. Derived units such as cubic centimeters are also widely used.

Liter

The liter is one of the most commonly used units in the metric system. It is equal to the volume of a cube with edges 10 cm long:
1 liter = 10 cm × 10 cm × 10 cm = 1000 cubic centimeters

This is the same as 0.001 cubic meters. The mass of one liter of water at a temperature of 4°C is approximately equal to one kilogram. Milliliters, equal to one cubic centimeter or 1/1000 of a liter, are also often used. Milliliter is usually denoted as ml.

Jill

Gills are units of volume used in the United States to measure alcoholic beverages. One jill is five fluid ounces in the British Imperial system or four in the American system. One American jill is equal to a quarter of a pint or half a cup. Irish pubs serve strong drinks in portions of a quarter jill, or 35.5 milliliters. In Scotland, portions are smaller - one fifth of a jill, or 28.4 milliliters. In England, until recently, portions were even smaller, just one-sixth of a jill or 23.7 milliliters. Now, it’s 25 or 35 milliliters, depending on the rules of the establishment. The owners can decide for themselves which of the two portions to serve.

Dram

Dram, or drachma, is a measure of volume, mass, and also a coin. In the past, this measure was used in pharmacy and was equal to one teaspoon. Later, the standard volume of a teaspoon changed, and one spoon became equal to 1 and 1/3 drachms.

Volumes in cooking

Liquids in cooking recipes are usually measured by volume. Bulk and dry products in the metric system, on the contrary, are measured by mass.

Tea spoon

The volume of a teaspoon is different in different measurement systems. Initially, one teaspoon was a quarter of a tablespoon, then - one third. It is the latter volume that is now used in the American measurement system. This is approximately 4.93 milliliters. In American dietetics, the size of a teaspoon is 5 milliliters. In the UK it is common to use 5.9 milliliters, but some diet guides and cookbooks use 5 milliliters. The size of a teaspoon used in cooking is usually standardized in each country, but different sizes of spoons are used for food.

Tablespoon

The volume of a tablespoon also varies depending on the geographic region. So, for example, in America, one tablespoon is three teaspoons, half an ounce, approximately 14.7 milliliters, or 1/16 of an American cup. Tablespoons in the UK, Canada, Japan, South Africa and New Zealand also contain three teaspoons. So, a metric tablespoon is 15 milliliters. A British tablespoon is 17.7 milliliters, if a teaspoon is 5.9, and 15 if a teaspoon is 5 milliliters. Australian tablespoon - ⅔ ounce, 4 teaspoons, or 20 milliliters.

Cup

As a measure of volume, cups are not defined as strictly as spoons. The volume of the cup can vary from 200 to 250 milliliters. A metric cup is 250 milliliters, and an American cup is slightly smaller, approximately 236.6 milliliters. In American dietetics, the volume of a cup is 240 milliliters. In Japan, cups are even smaller - only 200 milliliters.

Quarts and gallons

Gallons and quarts also have different sizes depending on the geographic region where they are used. In the Imperial system of measurement, one gallon is equal to 4.55 liters, and in the American system of measurements - 3.79 liters. Fuel is generally measured in gallons. A quart is equal to a quarter of a gallon and, accordingly, 1.1 liters in the American system, and approximately 1.14 liters in the Imperial system.

Pint

Pints ​​are used to measure beer even in countries where the pint is not used to measure other liquids. In the UK, milk and cider are measured in pints. A pint is equal to one-eighth of a gallon. Some other countries in the Commonwealth of Nations and Europe also use pints, but since they depend on the definition of a gallon, and a gallon has a different volume depending on the country, pints are also not the same everywhere. An imperial pint is approximately 568.2 milliliters, and an American pint is 473.2 milliliters.

Fluid ounce

An imperial ounce is approximately equal to 0.96 US ounces. Thus, an imperial ounce contains approximately 28.4 milliliters, and an American ounce contains approximately 29.6 milliliters. One US ounce is also approximately equal to six teaspoons, two tablespoons, and one eighth cup.

Volume calculation

Liquid displacement method

The volume of an object can be calculated using the fluid displacement method. To do this, it is lowered into a liquid of a known volume, a new volume is geometrically calculated or measured, and the difference between these two quantities is the volume of the object being measured. For example, if when you lower an object into a cup with one liter of water, the volume of the liquid increases to two liters, then the volume of the object is one liter. In this way, you can only calculate the volume of objects that do not absorb liquid.

Formulas for calculating volume

The volume of geometric shapes can be calculated using the following formulas:

Prism: the product of the area of ​​the base of the prism and the height.

Rectangular parallelepiped: product of length, width and height.

Cube: length of an edge to the third power.

Ellipsoid: product of semi-axes and 4/3π.

Pyramid: one third of the product of the area of ​​the base of the pyramid and the height. Post a question in TCTerms and within a few minutes you will receive an answer.

The United States of America is a country of cars. That is why talking about gasoline in this country is very important. In the article we will consider such aspects as fuel quality, brands and, of course, find out how much gasoline costs.

Overall fuel quality

As experts often note, gasoline in the United States is of very high quality: if a driver fills up with 91 or 93, he will get the quality he paid for. In some countries (unfortunately, Russia is one of them), fraud is widespread: diluting gasoline, i.e. adding substances that harm the engine. And in this case, the guarantee that the car is actually filled with premium fuel comes to naught, since the manufacturer’s assurance alone is not enough.

Trade marks

Now about the brands represented on the United States market.

Shell is a trademark of the large British-Dutch company Royal Dutch Shell. This brand of gasoline is one of the best-selling gasoline in the United States.

Chevron is a brand of the oldest American energy company, Chevron Corporation. Prices are about a quarter higher than Shell.

Mobil 1 is a brand that is somewhat behind the above in popularity.

The cost of gasoline in America

The price of fuel in the United States is indicated in gallons (there are 3.8 liters in one gallon). Somewhere in the statistics below we will find liters, somewhere - gallons, but for convenience we will still indicate most indicators in liters.

The average price of a liter of gasoline worldwide is $1.08. At the same time, the United States is among the countries with the lowest cost of gasoline: the price per liter is $0.72.

It is interesting that the leaders here are the oil and gas powers: Venezuela, Saudi Arabia, Qatar, etc. America, without having massive oil reserves, remains in the lead, although slightly behind Russia. In addition, fuel is several times cheaper than in European countries. For example, in , than in the USA almost 2 times.

The price of gasoline varies greatly by state. In addition, many people note that even in the same city the cost may vary. Thus, the most expensive gasoline is in California: in Los Angeles and San Francisco the cost is about $4 per gallon. For comparison, in Texas it is $1.95. In some cities, the price is completely low: for example, in Houghton (Michigan), the cost per gallon was once only $0.47.

If the gas station is located far from the city, the price increases accordingly. For example, at gas stations near Antelope Canyon the cost rises to $6.

Statistics say that the price varies depending on the month. So, the lowest cost is usually in the summer - $0.68. The highest is in the fall (about 0.75 per liter).

You can also note that they tend not only to grow, but also to fall, which is quite understandable because the market is developing. Residents of Russia, for example, should not expect prices to fall due to the colossal scale of corruption in the oil industry and the dominance of a single company in the market.

The price an American driver pays for gasoline already includes all taxes, so no additional payments will be required.

What makes up the cost of gasoline in the USA in comparison with Russia.

Gallons and liters are units of volume (usually liquids). The gallon is part of the obsolete English system of measures, and the liter is a non-system metric unit (can be used along with SI units). To convert gallons to liters, you need to know the conversion factor. Using this coefficient, you can write down the equation for converting one unit to another. There are also online calculators that quickly convert gallons to liters (and vice versa). Moreover, you can convert gallons to liters using a good graphing calculator.

Steps

Manually

Determine which variety of gallon you are faced with. Previously, in the English system of measures there were many units of measurement called the gallon: proof gallon, bulk (dry) gallon, liquid gallon, wine gallon, corn gallon. Over time, many varieties of galon were phased out (standardized), but today there are still three varieties of galon. So before converting, find out what type of gal you are dealing with.

• English (imperial) gallon. Generally, this variety of gallon is only used in the UK.
• US liquid (regular) gallon. In most cases, this type of gallon is used.
• US dry (solids) gallon. This variety is used quite rarely. Generally, if a value is given in gallons, it can be assumed to be US liquid gallons.

1. Find the conversion factor. The conversion factor for the three varieties of gallon can be found in a textbook or on the Internet.

   Write the conversion factor as a fraction. Recall that any fraction whose numerator is equal to the denominator is equal to 1. Such a fraction can be multiplied by any quantity, which will lead to a unit conversion, but the original value of the quantity will not change (because you multiplied the value by 1). To convert gallons to liters, use the following conversion factors, which are written as fractions:

   Write down the transformation equation. If you are given a value in gallons that you want to convert to liters, this can be done using a simple equation. Remember that the conversion factor is 1, so the original value (in gallons) will not change.

   Convert units of measurement. If the conversion factor is written correctly, simply multiply it by this value. Note that the gallons value is multiplied by a fraction that also has gallons as its denominator. Thus, gallons are reduced, but liters remain.

On an online calculator

Find an online calculator. To do this, enter “convert gallons to liters” (without quotes) into a search engine. Most likely, you will find many sites with corresponding online calculators. Open several sites and choose a calculator that suits you with its design and ease of use. Remember that the conversion result will be the same on any online calculator. Since there are several varieties of gallon, it is better to use a calculator in which you can indicate one or another variety.

Enter the gallon value you want to convert to liters. If you use an online calculator, you don't need a conversion factor - just enter the value in gallons and the value in liters will appear on the screen.

Convert to liters of the gallon variety. For example, to convert US gallons first and then UK gallons, you need to reconfigure the calculator. Typically, the online calculator will have a drop-down menu from which you can select a specific variety of gallon. Then enter the value in gallons and the result will appear on the screen.

On a graphing calculator

On your calculator, find the conversion function. Many good graphing calculators have it. Using this function, one unit of measurement can be converted to another. The conversion function is available on the Texas Instruments TI-83, TI-84Plus, and TI-86 calculators.

• On the TI-86, above the "5" button there is the word "Conv" (this is the conversion function). To activate this feature, first press “2” and then press “5”.

1. Enable the conversion feature. First, you need to tell the calculator what units of measurement you want to convert. Further steps depend on the calculator model, but, as a rule, they do not differ much.

The SI metric system of measurements is used throughout the world. Its basic units of measurement are the meter for length, the second for time, and the gram for weight. But volume is measured either in liters or cubic meters. Not all countries are included in this metric system; their units of measurement are different. In order to avoid confusion, you need to know other measures.

How much, for example, is one liter for an Englishman or an American? Let's try to figure this out. After all, the British are accustomed to measuring gasoline, beer and other liquids not in glasses or glasses, but in pints and gallons. And if you decide to visit countries where the metric system has never been used, then it is better to understand in advance all the intricacies of units of measurement.

The gallon originally came into being when determining the volume of eight pounds of wheat. Later, other types of units of volume measurement appeared, for example, the pint. In 1707, America began to use the British wine gallon, the size of which is 231 cubic inches. It was recognized as basic for measuring liquid substances. The British dry gallon and the American liquid pint soon emerged. It became a unit for measuring the volume of bulk solids and was called the American dry pint.

Reform and unification was approved by the British Parliament approximately two centuries ago, namely in 1824. As a result, all types were replaced by one unit: the imperial gallon. Ten pounds of distilled water, having a temperature of 62 degrees Fahrenheit - this is its real value. This amounts to 277.42 cu. inches.

What is a gallon?

This is a unit of volume of liquid or granular and liquid bodies. It operates primarily in the US and UK.

• American liquid gal is 3.785 liters;
• English dry gal - 4.5461 l;
• imperial gal - 4.546099 l;
• The proof gallon is considered a measure of the alcohol's capacity. In the US it is 1.89 liters, and in the UK the same unit is 2.594 liters.

In countries with the English system of measures It is customary to measure liquids and bulk products with this unit.

What other units of volume are there?

In Russia, it is customary to measure liquids in liters. A volume equal to one cubic decimeter is a liter. If you take a liter jar of water and weigh it, then this liquid will have a mass of about a thousand grams or one kilogram.

A pint is a quantity derived from a gallon; it is an octah of a gallon..

Forty-two US gallons equal a barrel to 159 liters. Due to some tax nuances, another variety arose, called the beer barrel. US citizens are familiar with the standard beer barrel, which is 31 US gallons in size. If converted to liters, it will be 117.3 liters.

It's interesting that:

• the unit of volume for Argentina, equal to 3.785 liters, is called frasco;
• and in Venezuela, Honduras, Colombia, Peru and other Latin American countries, the volume is measured in botels. Moreover, their sizes differ slightly from each other.

The conclusion is: gallons, quarts and pints are different, this difference is geographically dependent. That is, different parts of the globe have their own measure of liquids. The Imperial system of measurement assumes that one gallon is equal to 4.55 liters. The American system of measures indicates that a unit with the same name is 3.79 liters. There is also a quart, equal to a quarter of a gallon, which will hold 1.1 liters, following the American system, but for the imperial system the same value will be 1.14 liters.

Pints ​​also vary. An imperial pint, translated into our liters, will have a volume equal to 568.2 milliliters, while an American pint will have a volume of 473.2 milliliters.

In perfumery, standard tube sizes are used, they are measured in ounces. Typically, a standard tube of liquid cream has a capacity of 8 ounces, which in the metric system would be 235 milliliters.

An imperial ounce is much smaller than an American ounce and is 96% of it. After simple calculations, we can say that an imperial ounce contains approximately 28.4 milliliters of liquid, and an American ounce contains a little more (29.6 milliliters). If we measure this with the cutlery we know well, we can find out how many spoons are in an American ounce: it will be equal to six teaspoons or two tablespoons.

Canada, Ireland and some other countries use the English version. And, for example, Colombia or Nicaragua measure the amount of liquid according to the American system. There are many other variations of volume measurements. How many gallons does one barrel hold? It is known that it is equal to 37 gallons, this value is equal to one hundred and sixty-six liters.

This value is found by displacing the liquid. This method was invented by Archimedes. His famous “eureka” is familiar to any schoolchild. To find the volume of a body, it must be immersed in a liquid, having first measured its volume, then a new value must be calculated, knowing the geometry of the vessel and simple formulas. Next, by subtracting two quantities (obtained and known), you can calculate what you are looking for. For example, you need to lower an object into a jar that contains one liter of water, and the liquid level will increase to a certain value, let’s assume that the new volume will take up two liters, which means this object has a capacity of one liter.

This method is suitable for calculating the volume of substances or objects that do not absorb liquid. Otherwise, the calculation of dates by this method will be distorted and inaccurate.
