How the oil-barrel converter works
Enter a volume in bbl or liters. The second field updates immediately, and the center control reverses the conversion without changing the volume.
One oil barrel is exactly 158.987294928 liters
The standard oil barrel contains 42 US liquid gallons. Using the exact US gallon definition gives this relationship:
For the reverse calculation, divide liters by 158.987294928. Keep the full factor until the final display.
Useful checks for shipments and storage
- 1 bbl = 158.987294928 L. This is the base relationship.
- 10 bbl = 1,589.87294928 L. Ten barrels are just under 1.6 cubic meters.
- 50 bbl = 7,949.3647464 L.
- 1,000 L = 6.289810770432 bbl. This is the reverse direction.
A barrel is not always an oil barrel
The calculator uses the petroleum unit marked bbl. Beer, wine, dry-goods and physical shipping barrels can have different capacities. Confirm the unit in the source document before converting.
This is a volume calculation. Converting the result to mass requires the product density and, for precise inventories, the stated reference conditions.
Questions about bbl and liters
The main checks concern the barrel type, the exact factor and the difference between volume and mass.
How many liters are in one oil barrel?
Exactly 158.987294928 liters.
How do I convert oil barrels to liters?
Multiply the number of barrels by 158.987294928.
How do I convert liters to barrels?
Divide liters by 158.987294928.
Is bbl a measure of weight?
No. bbl measures volume; weight depends on the liquid density.
Can I use this factor for beer barrels?
No. This calculator uses the standard oil barrel, while beverage barrels may have other definitions.
