Oil Barrels: A Unit of Volume

Oil barrels are a unit of volume that are used to measure crude oil and petroleum products, such as gasoline, diesel, jet fuel, etc. They are different from fluid barrels, which are used to measure other liquids, such as beer, wine, water, etc. Oil barrels 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 Oil Barrels

An oil barrel is defined as 42 US gallons or 0.159 cubic meters in the US customary system of measurement. It is equivalent to 34.9723 imperial gallons or 158.987 liters in the imperial system. An oil barrel is also equal to 5.6146 cubic feet or 6.2898 oil barrels in the metric system.

History of Oil Barrels

The origin of the term barrel as a unit of measure is uncertain, but it may have derived from the French word baril, which means a small cask or keg. Barrels have been used since ancient times to store and transport various goods, especially liquids and dry grains. The size and shape of barrels 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 oil barrels as a unit of measure dates back to the 19th century, when the petroleum industry emerged in the United States and other countries. The first oil wells produced oil that was stored in wooden barrels that were readily available from the whiskey industry. The standard size of these barrels was 42 US gallons, which was also the size of a tierce, a unit of measure for wine and salt.

The use of oil barrels as a unit of measure became more widespread as the oil market developed and expanded globally. Oil barrels were convenient for measuring and transporting large quantities of oil across long distances by rail, ship, pipeline, etc. Oil barrels were also used for pricing and trading oil in various markets and exchanges.

How to Convert Oil Barrels

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

• To convert oil barrels to cubic meters: multiply by 0.159
• To convert oil barrels to liters: multiply by 158.987
• To convert oil barrels to cubic feet: multiply by 5.6146
• To convert oil barrels to gallons (US): multiply by 42
• To convert oil barrels to gallons (UK): multiply by 34.9723
• To convert oil barrels to BOE: divide by 6.2898

Where Oil Barrels are Used

Oil barrels are mainly used in the United States and some other countries that still use the US customary system of measurement. They are often used for measuring and reporting the production, consumption, reserves, and trade of crude oil and petroleum products.

In some countries that use the metric system of measurement, such as Canada and Australia, oil barrels are sometimes used as an informal or approximate unit of volume for certain types of crude oil or petroleum products. For example, in Canada, heavy crude oil is sometimes sold by the barrel, which is equivalent to about 159 liters or 0.159 cubic meters.

In some countries that have their own traditional units of volume based on barrels or similar containers, such as India and China, oil barrels are not commonly used or recognized. Instead, they use units such as tonnes (about 7.33 barrels), kilolitres (about 6.29 barrels), or tonnes of oil equivalent (about 7.1 barrels).

Example Conversions of Oil Barrels to Other Units

Here are some examples of converting oil barrels to other units of volume:

• 1 oil barrel = 0.159 cubic meters
• 2 oil barrels = 317.974 liters
• 3 oil barrels = 16.8438 cubic feet
• 4 oil barrels = 168 gallons (US)
• 5 oil barrels = 174.8615 gallons (UK)
• 6 oil barrels = 0.9534 BOE
• 7 oil barrels = 1.113 BOE

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
