1 gallon (gal) = 3.78541178 liter (l). Gallon (gal) is a unit of Volume used in Standard system. Liter (l) is a unit of Volume used in Metric system.

Gallons: A Unit of Volume

Gallons are a unit of volume that are used to measure liquids, such as water, milk, oil, wine, etc. They are also used to measure some dry goods, such as grains, fruits, nuts, etc. They are different from cups, which are a smaller unit of volume. They are also different from liters, which are a larger unit of volume. They are also different from barrel of oil equivalent (BOE), which is a unit of energy based on the approximate energy released by burning one barrel of crude oil.

Definition of Gallons

A gallon is defined as a unit of liquid capacity in both the US customary and imperial systems of measurement. However, the size of a gallon varies depending on the type of gallon used:

  • A US liquid gallon is equal to 3.785 liters or 0.833 UK gallons in the metric system. It is equivalent to 231 cubic inches or 128 fluid ounces in the US customary system.
  • A US dry gallon is equal to 4.405 liters or 0.969 UK gallons in the metric system. It is equivalent to 268.8 cubic inches or 148.9 fluid ounces in the US customary system.
  • A UK gallon is equal to 4.546 liters or 1.2 US liquid gallons in the metric system. It is equivalent to 277.4 cubic inches or 160 fluid ounces in the imperial system.

History of Gallons

The origin of the term gallon as a unit of measure is uncertain, but it may have derived from the Old French word galon, which means a large liquid measure. Gallons have been used since ancient times to store and transport various liquids and dry goods. The size and shape of gallons varied depending on the type and quantity of the goods, the availability of materials, and the customs of different regions and countries.

The use of gallons as a unit of measure dates back to the medieval times, when the European system of measurement was established. The standard size of these gallons was based on the wine gallon, which was originally defined as the volume of eight pounds of wine at 62 °F. The gallon was convenient for measuring and dividing larger amounts of liquids and dry goods.

The use of gallons as a unit of measure continued until the 20th century, when the metric system of measurement was adopted in most countries. The gallon was gradually replaced by units such as liters, kilograms, etc. However, some countries and regions still use gallons for certain types of liquids and dry goods, especially in the United States and the United Kingdom and its former colonies.

How to Convert Gallons

To convert gallons to other units of volume, one can use the following formulas:

  • To convert US liquid gallons to liters: multiply by 3.785

  • To convert US liquid gallons to cubic inches: multiply by 231

Where Gallons are Used

Gallons are mainly used in some countries and regions that use the US customary system or the imperial system of measurement. They are often used for measuring and adding liquids such as water, milk, oil, wine, etc., and dry goods such as grains, fruits, nuts, etc., to recipes.

In some countries that use the metric system of measurement, such as Canada and Australia, gallons are not commonly used or recognized. Instead, they use units such as liters, kilograms, etc.

Example Conversions of Gallons to Other Units

Here are some examples of converting gallons to other units of volume:

  • 1 US liquid gallon = 3.785 liters

  • 2 US liquid gallons = 462 cubic inches

  • 3 US liquid gallons = 384 fluid ounces

  • 4 US liquid gallons = 3.332 UK gallons

Liters - A Unit of Volume

Definition of the Liter

A liter (international spelling) or liter (American English spelling) (SI symbols L and l) is a unit of volume that is used in the metric system. It is defined as the volume of a cube with sides of 10 centimeters (0.1 meter) in length.

One liter is equal to 1000 cubic centimeters, 0.001 cubic meters, or 1 cubic decimeter.

History of the Liter

The liter is derived from the litron, which was an old French unit of volume that was based on the Greek unit of weight called the litra. The litron was equal to about 0.831 liters. The word liter was first used in 1795 by the French chemist Antoine Lavoisier as a unit of volume for liquids and gases. The liter was originally defined as the volume of one kilogram of pure water at 4 °C and standard atmospheric pressure.

The liter was later redefined several times based on different physical standards, such as a platinum-iridium cylinder and a wavelength of light. The current definition of the liter, adopted in 1964, is based on the cubic meter, which is the SI unit of volume. The liter is not an SI unit, but it is accepted by the CGPM (the standards body that defines the SI) for use with the SI.

How to Convert Liters

To convert liters to other units of volume, you need to multiply or divide by the appropriate conversion factor. Here are some common conversion factors and examples:

  • To convert liters to cubic centimeters, multiply by 1000.
    • Example: 2 L x 1000 = 2000 cm3
  • To convert liters to cubic meters, multiply by 0.001.
    • Example: 2 L x 0.001 = 0.002 m3
  • To convert liters to cubic decimeters, multiply by 1.
    • Example: 2 L x 1 = 2 dm3
  • To convert liters to gallons (US liquid), multiply by 0.264.
    • Example: 2 L x 0.264 = 0.528 gal
  • To convert liters to bushels (US), multiply by 0.037.
    • Example: 2 L x 0.037 = 0.074 bu
  • To convert liters to barrels (oil), multiply by 0.0063.
    • Example: 2 L x 0.0063 = 0.0126 bbl

To convert other units of volume to liters, you need to divide by the appropriate conversion factor. Here are some common conversion factors and examples:

  • To convert cubic centimeters to liters, divide by 1000.
    • Example: 2000 cm3 / 1000 = 2 L
  • To convert cubic meters to liters, divide by 0.001.
    • Example: 0.002 m3 / 0.001 = 2 L
  • To convert cubic decimeters to liters, divide by 1.
    • Example: 2 dm3 / 1 = 2 L
  • To convert gallons (US liquid) to liters, divide by 0.264.
    • Example: 0.528 gal / 0.264 = 2 L
  • To convert bushels (US) to liters, divide by 0.037.
    • Example: 0.074 bu / 0.037 = 2 L
  • To convert barrels (oil) to liters, divide by 0.0063.
    • Example: 0.0126 bbl / 0.0063 = 2 L

Where Liters are Used

Liters are used for measuring various materials and substances in different countries and applications.

Some examples are:

  • In most countries that use the metric system, liters are used for measuring liquids and gases, such as water, milk, juice, soda, beer, wine, oil, fuel, air, and oxygen.
  • In some countries that use the imperial system, such as the United States and Canada, liters are used for measuring some liquids and gases, such as soft drinks, bottled water, milk, and propane.
  • In the European Union, liters are used for measuring fuel consumption and carbon dioxide emissions of vehicles.
  • In the medical industry, liters are used for measuring blood volume, urine output, and intravenous fluid administration.
  • In the scientific industry, liters are used for measuring chemical solutions, reactions, and concentrations.

Example Conversions of Liters to Other Units

Here are some example conversions of liters to other units of volume:

  • 1 L = 1000 cm3
  • 1 L = 0.001 m3
  • 1 L = 1 dm3
  • 1 L = 0.264 gal
  • 1 L = 0.037 bu
