History of liter [L, l] unit

The liter originated in France during the metrication reforms of the late eighteenth century. Its name derives from the French “litron,” a unit associated with measuring grain. The 1795 French metric system defined the liter as one cubic decimeter. Although later standards emphasized the cubic meter as the fundamental volume unit, the liter remained widely accepted. In 1964, the General Conference on Weights and Measures clarified its relationship to the cubic decimeter, and modern international usage recognizes the liter as a non-SI unit accepted for use with the SI.
