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 inch is an imperial unit of volume equal to the space occupied by a cube one inch on each side.
1 in³ = 16.387064 mL = 16.387064 cm³. There are 1,728 in³ in one cubic foot.
To mL: multiply by 16.387064. To liters: multiply by 0.016387064. To cubic centimeters: multiply by 16.387064.
Engine displacement (classic American V8s measured in cubic inches), small container volumes, and manufacturing specifications.
The iconic Chevrolet 'small block 350' engine has a displacement of 350 cubic inches (5.7 liters). A golf ball is about 2.48 in³.
Confusing cubic inches with fluid ounces — 1 in³ ≈ 0.554 fl oz (US). They are not equivalent.
Think of a standard die (game dice) — it's roughly 1 in³. A cubic inch of water weighs about 0.578 ounces.
