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

Cubic Millimeters - A Unit of Volume

Definition of the Cubic Millimeter

A cubic millimeter (symbol mm3 or cu mm) is a unit of volume that corresponds to the volume of a cube with sides of 1 millimeter (0.001 meter) in length. It is also equivalent to 0.001 milliliter, which is a unit of volume in the metric system.

One cubic millimeter is equal to 0.000000001 cubic meters, 0.00006102374 cubic inches, or 0.000000264172 gallons.

History of the Cubic Millimeter

The cubic millimeter is derived from the millimeter, which is a unit of length that was introduced in France in 1795 as part of the metric system. The millimeter was defined as one thousandth of a meter, which is the base unit of length in the metric system. The meter was originally defined as one ten-millionth of the distance from the equator to the North Pole along a meridian, but later redefined based on various physical standards, such as a platinum-iridium bar and a wavelength of light. The current definition of the meter, adopted in 1983, is based on the speed of light in vacuum.

The cubic millimeter was first used as a unit of volume for measuring very small amounts of liquids and gases, such as medicine, perfume, ink, and blood. The cubic millimeter was also used for measuring some solids, such as sugar, salt, and flour. The cubic millimeter was adopted as a standard unit of measure in many countries that use the metric system, such as France, Germany, Italy, Spain, and Sweden.

How to Convert Cubic Millimeters

To convert cubic millimeters 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 cubic millimeters to cubic meters, multiply by 0.000000001.
