Why international crude oil to use barrels as a unit?
Gas, coal, diesel prices in the American market to cents a gallon for the unit, the same above formula can be used to converted to U.S. dollars / ton units. For example, the United States of San Francisco in July 27, 1993 93 unleaded gasoline price of 54 cents per gallon, the conversion method is derived as follows:93# price =54.0 cents a gallon of unleaded gasoline; 54.0*0.01*42 cents / barrel (1 barrels of =42 gallons), 54.0*0.01*42*8.5 dollars / ton (about 1 tons of gasoline and 8.5 barrels), 54.0*3.57* (for 3.57 cents a gallon of gasoline by conversion of U.S. dollars / ton conversion coefficient =192.78 USD / ton)Table 1 conversion table of volume and weight of crude oil and oil
The 6.29 is divided by the density conversion coefficient formula for 1 tons of oil is equal to the number of barrels of oil. The oil density size and conversion coefficient of the reciprocal relationship, such as: Daqing crude oil density of 0.8602, winning 101 crude oil density of 0.9082, can be respectively:Conversion coefficient of Daqing crude oil =6.29/0.8602=7.31, conversion coefficient of Shengli crude oil =6.29/0.9082=6.93
1 conversion between volume and weightThe conversion between the volume and the weight of the unit must be introduced into the density of P. crude oil and the density of the finished oil Pt expressed at a certain temperature state, the volume of oil per cubic meter is p tons:Volume of one ton of oil =1/p cubic metersA ton of oil equivalent barrels =1/p * 6.29 barrels (oil)
Barrels and two tons of crude oil is our common unit of quantity. OPEC and the western countries. As the number of units of crude oil is usually expressed in barrels, and Chinese and Russia and other countries are commonly used metric units as the quantity of crude oil. The conversion between tons and barrels: 1 ton equivalent to about 7 barrels, if the oil is lighter (dilute) is equivalent to about 1 tons, or 7.2 barrels of 7.3 barrels. Despite the conversion relation between fixed tons and tons of barrels, but because the quality is, the barrel is a unit of volume, and the variation range of the density of crude oil in large transactions such as different units of calculation, the results are different.
