The US barrel is a unit of volume equal to 31.5 US gallons (about 119.24 liters), used for various liquid commodities.
1 US barrel = 31.5 US gal = 119.24 L = 0.11924 m³ = 4,032 US fl oz.
To liters: multiply by 119.24. To US gallons: multiply by 31.5. To UK barrels: multiply by 0.729.
Brewery production volumes, whiskey barrel aging, wine production, and bulk liquid commodity trading.
A bourbon whiskey barrel is 53 gallons (200 L), larger than the standard US liquid barrel. Barrel sizes vary by commodity and country.
Confusing the US liquid barrel (31.5 gal) with the petroleum barrel (42 gal). Always specify which barrel type.
There are several different 'barrel' sizes. US liquid = 31.5 gal, US oil = 42 gal, UK = 36 imperial gal. Always specify!
The cubic kilometer is a unit of volume equal to a cube one kilometer on each side (10⁹ m³), used for extremely large volumes.
1 km³ = 10⁹ m³ = 10¹² L = 10¹⁵ mL. One cubic mile ≈ 4.168 km³.
To liters: multiply by 10¹². To cubic meters: multiply by 10⁹. To cubic miles: multiply by 0.23990.
Measuring lake volumes (Lake Baikal ≈ 23,615 km³), ice sheet volumes, and major reservoir capacities.
Earth's total ocean volume is about 1.335 billion km³. All human-made reservoirs combined hold only ~8,000 km³.
Underestimating the scale — 1 km³ = 10⁹ m³ = one trillion liters. It is a colossal volume.
Imagine a cube 1 km on each side — it would hold enough water to fill 400,000 Olympic swimming pools.
