Fluid ounce (oz - U.S. liquid measure), volume
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).
