A litre is defined as a special name for a cubic decimetre (1 L ≡ 1 dm3). Hence 1 L ≡ 0.001 m3 ≡ 1000 cm3, and 1000 L ≡ 1 m3 (exactly).
From 1901 to 1964, the litre was defined as the volume of one kilogram of pure water at 4 °C and 760 millimetres of mercury pressure. During this time, a litre was about 1.000028 dm3. In 1964 this definition was abandoned in favour of the current one.
