The imperial (UK) gallon is defined as exactly 4.54609 liters, about 20% larger than the US liquid gallon. It survives in British fuel-economy figures (miles per gallon) and is the base of the imperial system of capacity, in which the pint, quart, peck and bushel are all defined relative to it.

The cubic millimeter (mm³) is the volume of a cube 1 mm on each side and equals one microliter. It is used for very small quantities in engineering, medicine and materials science, for example in blood cell counts reported per mm³.
