The liter (l) is a metric unit of volume originally defined as that of 1 kilogram of water at the temperature of maximum density (1.000028 dm3), but redefined in 1964 as exactly equal to 1 cubic decimeter (= 1 dm3). A liter is equivalent to 0.22 imperial gallons or 0.2642 US gallons. The liter is not recommended for use alongside SI units.
