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 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.
