US, Imperial and kitchen measures

Cooks move a recipe between cups, tablespoons and milliliters, drivers compare fuel priced per liter and per gallon, and gardeners and builders size tanks, soil and concrete in cubic feet and cubic yards. Check which gallon a source means: 5 US gallons is 18.92705892 L, while 5 Imperial gallons is 22.73045 L. The same goes for the pint: a UK pint of beer is 568.26125 ml, or 19.21519881 US fluid ounces, and a 75 cL wine bottle is 25.36051703 US fl oz. The page is the Volume tab of the full unit converter, so length, weight and the other tabs sit above the fields.

How the factors are built

Every unit is an exact ratio to the liter, and each conversion goes through liters. US liquid units come from the 231 in³ gallon of 3.785411784 L: quart = gal/4, pint = gal/8, cup = gal/16, fluid ounce = gal/128, tablespoon = gal/256, teaspoon = gal/768. The Imperial gallon is exactly 4.54609 L; the Imperial quart is 1/4 of it (1.1365225 L), the pint 1/8 (568.26125 ml) and the fluid ounce 1/160 (28.4130625 ml). The metric prefixes are exact too: 1 dL = 100 ml, 1 cL = 10 ml and 1 kL = 1,000 L. Cubic inches, feet and yards follow from 1 in = 0.0254 m. Example: 1 ft³ = 0.3048³ m³ = 28.31684659 L = 7.480519481 US gal. The ratios are exact, and only the shown result is cut to 10 significant digits, which is why 1 L reads 0.2641720524 US gal. US dry measures and an Imperial cup are not included.
