1 ton crude oil is about 7 barrels. If the oil quality is light (thin), 1 ton is about 7.2 barrels or 7.3 barrels. The specific gravity of crude oil varies from 0.8 to 1.0 kg/L, so the weight of a barrel of crude oil is different. About 128- 142 kg.

The unit of crude oil in western countries, such as the Organization of Petroleum Exporting Countries, Britain and the United States, is usually expressed as "barrel" (the unit that the west likes), while China and Russian countries often use tons as the unit of crude oil.

Brief introduction of crude oil:

Traditionally, crude oil is called crude oil. Dark brown viscous oily liquid with green fluorescence and special smell. It is a mixture of alkanes, cycloalkanes, aromatic hydrocarbons and olefins.

The main components are carbon and hydrogen, accounting for 83 ~ 87% and 1 1 ~ 14% respectively. There are also a small amount of sulfur, oxygen, nitrogen and trace elements such as phosphorus, arsenic, potassium, sodium, calcium, magnesium, nickel, iron and vanadium. Specific gravity 0.78 ~ 0.97, molecular weight 280 ~ 300, freezing point -50 ~ 24℃. Crude oil can be refined to obtain various products, such as fuel oil, solvent oil, lubricating oil, grease, paraffin, asphalt, liquefied gas, aromatic hydrocarbons and so on. , and provide fuel, raw materials and chemical products for all sectors of the national economy.
