To liters: multiply by 158.987. To US gallons: multiply by 42. To cubic meters: multiply by 0.158987.
1 oil barrel = 42 US gal = 158.987 L = 34.97 UK gal = 5,376 US fl oz.
For example, 1 Barrel (Oil) (bbl (oil)) = 1.589873e-7 Gigaliter (GL).

The oil barrel is a unit of volume equal to 42 US gallons (approximately 158.987 liters), the standard for measuring crude oil and petroleum products.
1 oil barrel = 42 US gal = 158.987 L = 34.97 UK gal = 5,376 US fl oz.
To liters: multiply by 158.987. To US gallons: multiply by 42. To cubic meters: multiply by 0.158987.
Crude oil trading and pricing, refinery throughput, national oil production statistics, and petroleum reserve reporting.
Global oil consumption is about 100 million barrels per day. Oil is no longer actually shipped in barrels — the unit persists purely as a standard of measurement.
Confusing the oil barrel (42 gal) with the US liquid barrel (31.5 gal). Always use 'bbl (oil)' or specify the type.
Oil is priced per barrel (~42 gallons). When you see '$70/barrel,' that means about $1.67/gallon before refining and distribution costs.
The gigaliter is a unit of volume equal to one billion liters (10⁹ L), or one million cubic meters.
1 GL = 10⁹ L = 10⁶ m³ = 1,000 ML. One teraliter = 1,000 GL.
To liters: multiply by 10⁹. To cubic meters: multiply by 10⁶. To megalliters: multiply by 1,000.
Reporting dam capacities (e.g., Hoover Dam stores ~35 GL), regional water budgets, and flood volumes.
Sydney Harbour holds approximately 500 GL of water. Lake Mead (behind Hoover Dam) has a capacity of about 35,200 GL.
Underestimating the scale — 1 GL = one billion liters = one million cubic meters. It is an enormous volume.
Think 'giga = billion.' 1 GL would fill 400 Olympic pools. It's the unit for dams and large reservoirs.
