1 ton crude oil is about 7.33 barrels of crude oil. It should be noted that since the ton is the unit of mass and the barrel is unit of volume, and the density of crude oil may change, the conversion rate may be different under different conditions. For example, if the crude oil is very thin, the ratio may be close to 7.2 or 7.3 barrels. Traditionally, crude oil is called crude oil.
