The liter (L) is a commonly used metric unit of volume for measuring the capacity of containers and the volume of liquids. It is a versatile and widely recognized unit for expressing volumes in everyday life, as well as in scientific and commercial contexts. Whether you're pouring a glass of water or quantifying the fuel capacity of a vehicle, the liter plays a crucial role in volume measurement.

Definition and Usage

The liter is defined as the volume of a cube with sides measuring one decimeter (0.1 meters) in length. It is equal to one thousand cubic centimeters (cm³) or one-tenth of a dekaliter (10 L). The liter is extensively used for measuring liquids, beverages, and other substances in containers of various sizes.
