How many kilos per barrel
1 barrels =158.98 liters =42 gallon. U.S. 1 gallon =3.785 liters, 1 gallons = 4.546 liters. If the volume is converted to weight, and the density of crude oil. Assuming a crude oil density of 0.99 kg / L, then the weight of a barrel of crude oil is 158.98 x 0.99= kg of 157.3902
1 tons is equivalent to about 7 barrels, if the oil is lighter (dilute) is about equal to the amount of 7.2 tons or 7.3 barrels per day (or less), or about 1 barrels. Europe and the United States and other countries of the gas station, usually do with gallon units, China's gas stations are used to raise the valuation.
Because the density of oil produced varies from place to place, the weight of a barrel of oil is not the same. Between 128-142 kg.
