a cube of water ten centimeters per side, weighing exactly one rebellious kilogram
means A metric unit of volume equal to 1,000 cubic centimeters, roughly the amount of liquid in a standard sports bottle.
from From French 'litre', borrowed from the older 'litron', a French unit of measure for grain — which traces back through Medieval Latin 'litra' to the Greek 'litra', a unit of weight used in Sicily. So a word that began as a measure of mass drifted into a measure of volume, fittingly stubborn for a unit that ties one to the other. The spelling 'liter' is the American simplification of the British and French '-re'.
