how many liters is in a barrel of oil
Barrel (unit) In the worldwide oil industry, an oil barrel is defined as 42 US gallons, which is about 7002159000000000000â™ 159 litres[10] or 35 imperial gallons.[11] In Canada, oil companies measure oil in cubic metres but convert to barrels on export, since most of Canada's oil production is exported to the US. The nominal conversion factor is 1 cubic metre = 6.2898 oil barrels,[12] but conversion is generally done by custody transfer meters on the border since the exact conversion factor depends on oil density and temperature.
