Volume & Capacity Converter
Convert between volume units — metric (mL, cL, L, m³, cm³), cubic imperial (cubic inch, cubic foot) and US/imperial liquid measures (gallon, quart, pint, fluid ounce, tablespoon, teaspoon, gill), plus the bushel and oil barrel. Pick any two; it runs entirely in your browser.
Factors are exact or sourced standards anchored to the litre (1 US gallon = 3.785411784 L, 1 imperial gallon = 4.54609 L, 1 cubic foot = 28.316846592 L, 1 US bushel = 2,150.42 cubic inches). US and imperial measures differ — a US gallon is smaller than an imperial gallon, and a US fluid ounce is slightly larger than an imperial one — so each unit below is labelled US or Imperial to keep results unambiguous.
