Facts about the Liter
The liter is a metric unit of volume accepted for use with the SI, defined as 1 cubic decimeter or 1,000 cubic centimeters (cm³).
The liter was originally defined in 1795 as the volume of one kilogram of water at 4°C and later redefined to align precisely with cubic measurements in the metric system.
Liters are commonly used around the world to measure beverages (like water and soda), vehicle fuel capacity, and household liquids such as milk, detergent, and paint.
