Liter (l)

Liter (L) is a unit of volume in the International System of Units (SI), accepted for use with the SI, and also known as the metric system. The liter is not an SI unit but is accepted for use with the SI. The symbol for liter is "L", although the lowercase "l" is also sometimes used. It is defined as the volume of a cube that is 10 centimeters on a side, with 1 liter equaling 1 cubic decimeter (dm^3), 1,000 cubic centimeters (cm^3), or 1/1,000 cubic meter (m^3).

History[edit | edit source]

The liter was introduced in France in 1795 as one of the new French Revolutionary units and was based on the volume of one kilogram of water, which was almost exactly one liter. Over time, the definition of the liter has undergone several revisions. In 1964, at the 12th General Conference on Weights and Measures (CGPM), the liter was redefined as exactly 0.001 cubic meters.

Usage[edit | edit source]

The liter is widely used around the world for many everyday measurements. It is commonly used to express the volume of liquids, such as water, beverages, milk, fuel, and so on, as well as for labeling the capacity of containers. In addition to its use in the culinary and automotive industries, the liter is also used in the medical field, particularly in labeling the volume of liquid medications and for blood volume measurements.

The liter is part of the metric system, and its conversions are straightforward:

1 liter = 1,000 milliliters (mL)
1 liter = 0.001 cubic meters (m^3)
1 liter = 1 cubic decimeter (dm^3)

For conversions to non-metric units:

1 liter ≈ 0.264172 gallons (US)
