Using this volume converter
Compare tank capacities, liquid quantities and geometric volumes in litres, cubic metres or US gallons.
A cubic metre contains 1,000 litres. Converting volume does not calculate a tank's working capacity, freeboard or the mass of its contents.
Check before using the result
- Gallon here means US liquid gallon. An Imperial gallon is different and cannot use the same factor.
- Oil barrel means 42 US gallons. A physical drum or container called a barrel may have a different rated capacity.
Definitions and method: NIST: unit conversion factors and rounding. Calculations use double-precision arithmetic; the display precision can be adjusted above.
