What Is a Liter?
The liter (L) is a metric unit widely used around the world to measure both liquids and certain non-liquid volumes (like container or engine capacity). It is defined as:
- 1 liter = 1,000 cubic centimeters (cm³)
- 1 liter = 1 cubic decimeter (dm³)

Originally based on the volume of 1 kg of water at its densest point, the definition was simplified to exactly 1 dm³ for consistency.
