Liquid Volume Converter

How this works

All liquid volume units convert through a common base — this calculator uses milliliters. A U.S. fluid ounce is defined as 29.5735 mL, and every other unit (cup, pint, quart, gallon, liter) is a fixed multiple of a fluid ounce or milliliter, so converting between any two is just multiplication and division through that shared base.
