A Liter is a metric volume unit equal to 1,000 cubic centimeters, 1 cubic decimeter or 33.814 fluid ounces in the imperial system. The volume is equivalent to a cube with 10cm on each of its sides.
The liter was defined in 1795, in the French metric system introduced after the Revolution, as a cubic decimeter. From 1901 to 1964 it was redefined as the volume of 1 kilogram of water, which made it 1.000028 cubic decimeters.
When converting volume measurements, be sure to remember that the dimensions are cubed and so doubling the sides of a cube will increase the volume by a factor of eight.
