What Is a Liter (L)?
A liter (symbol: L or l) is a metric unit of volume equal to 1 cubic decimeter (dm³), 1,000 cubic centimeters (cm³), or 1/1,000 cubic meters (m³). While it’s not an SI base unit, it is accepted for use with the International System of Units.
Historical Note: From 1901 to 1964, a liter was defined as the volume of one kilogram of pure water at its maximum density under standard atmospheric pressure. This definition was later revised back to a cubic measurement because factors like temperature, pressure, and purity made the earlier version inconsistent.
Current Use: Liters are used worldwide to measure liquid quantities such as beverages, cooking liquids, fuel for vehicles, water bottles, and even non-liquid volumes like car trunks, refrigerators, backpacks, and microwaves.
