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 megaliter is a unit of volume equal to one million liters (10⁶ L), or 1,000 cubic meters.
1 ML = 10⁶ L = 1,000 m³ = 1,000 kL. One gigaliter = 1,000 ML.
To liters: multiply by 10⁶. To cubic meters: multiply by 1,000. To gallons (US): multiply by 264,172.
Municipal water supply reporting, reservoir levels, agricultural water allocation, and wastewater plant throughput.
An Olympic swimming pool holds 2.5 ML. A small town might use 1–5 ML of water per day.
Confusing ML (megaliter) with mL (milliliter) — they differ by a factor of 10⁹. Capitalization matters!
ML vs. mL: uppercase M = mega (million), lowercase m = milli (thousandth). Always check the case carefully.
