# liter (l)

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 dm^{3}), but redefined in 1964 as exactly
equal to 1 cubic decimeter (= 1 dm^{3}). A liter is equivalent to
0.22 imperial gallons or 0.2642 US gallons. The liter is not recommended
for use alongside SI units.
