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 US liquid quart is a unit of volume equal to 32 US fluid ounces, or approximately 946.353 milliliters.
1 US qt = 2 US pt = 4 US cups = 32 US fl oz = 1/4 US gallon ≈ 946.353 mL.
To liters: multiply by 0.946353. To mL: multiply by 946.353. To UK quarts: multiply by 0.832674.
Buying motor oil (sold by the quart), milk containers, paint coverage calculations, and cooking large recipes.
A US quart is slightly less than 1 liter (946 mL vs. 1,000 mL). Saying 'a quart is about a liter' is a useful rough approximation.
Assuming a quart equals a liter — it's close but 5.4% smaller. When substituting in recipes, this error accumulates.
A quart is roughly a liter. 'Quart' comes from 'quarter' — it's 1/4 gallon. Chain: 4 cups → 2 pints → 1 quart → 1/4 gallon.
