How Volume Units Relate

Volume conversions get more complicated than length or weight because both the metric system (milliliters, liters) and the US customary system (fluid ounces, cups, gallons) are in everyday use, and the US and UK versions of "fluid ounce" and "gallon" aren't the same size. This page uses US customary definitions throughout.
