Conversion method of petroleum volume and weight unit

1. Conversion between volume and weight units

Density P must be introduced into the conversion of volume and weight units. The density pt of crude oil and refined oil refers to the oil weight of P tons per cubic meter at a certain temperature. The conversion relationship is:

Volume of one ton of oil = 1/p m3.

The number of barrels equivalent to one ton of oil = 1/p * 6.29 barrels (oil)

Dividing the density by 6.29 is the formula for calculating the conversion coefficient of how many barrels of oil 1 ton of oil is equal to. This conversion coefficient is related to the density of oil products, and there is a mutual relationship. For example, the density of Daqing crude oil is 0.8602, and the density of Shengli 10 1 oil depot is 0.9082, respectively:

Daqing crude oil conversion coefficient =6.29/0.8602=7.3 1, Shengli crude oil conversion coefficient =6.29/0.9082=6.93.

The calculation method of petroleum products is the same. If the density of a certain gasoline is 0.739, the calculation result is: 1 ton gasoline equals 8.5 1 barrel; The density of a diesel oil is 0.86, and the calculation result is that 1 ton diesel oil is equal to 7.3 1 barrel. And so on. Table 1 lists the conversion factors of tons and barrels of conventional oil and ordinary crude oil at home and abroad.

The price of gasoline, coal and diesel in the American market is in cents/gallon, which can also be converted into dollars/ton by the above formula. For example,1July 27, 993, the price of unleaded gasoline No.93 in San Francisco, USA was 54.0 cents/gallon, and its conversion method was deduced as follows:

93# unleaded gasoline price =54.0 cents/gallon; 54.0*0.0 1*42 cents/barrel (1 barrel =42 gallons), 54.0*0.0 1*42*8.5 USD/ton (about 1 ton gasoline and 8.5 barrels), 54.0.
