Facts about fluid ounce (oz)

A fluid ounce is a unit of volume in both the Imperial system of units and the U.S. customary units system. However, the two measures are not quite the same: The Imperial fluid ounce is 1/160 of an imperial gallon or 1/20 of an imperial pint or 8 fluid drams, about 1.734 cubic inches or 28.4130625 millilitres. This volume of water weighs very nearly 1 avoirdupois ounce (it is the volume occupied by one ounce at 62 °F (16.7 °C), weighed in air with brass weights). See all conversions for ounces here.

Facts about milliliter (ml)

A millilitre (ml) equals a thousandth of a litre, or 0,001 litre. The litre (spelled litre in Commonwealth English and liter in American English) is a unit of volume. There are two official symbols, the Latin letter el in both cases: l and L. The litre is not an SI unit but is accepted for use with the SI. The SI unit of volume is the cubic metre (m³).
