litersystemet

The litersystemet, or liter system, is a metric unit of volume. It is derived from the meter, the base unit of length in the International System of Units (SI). One liter is defined as the volume of a cube with sides of 10 centimeters. This means a liter is equivalent to 1,000 cubic centimeters, often denoted as cm³ or cc.

The liter is a practical unit for everyday use, commonly employed for measuring liquids such as water, milk, and fuel. It is also used in various scientific and industrial contexts. While not an SI base unit itself, the liter is accepted for use with the SI. Its symbol is "L" or "l".

Common multiples and submultiples of the liter are also in use. The milliliter (mL) is one-thousandth of a liter and is frequently used for smaller volumes, like in medicine or cooking. The kiloliter (kL), equal to 1,000 liters, is used for larger quantities, such as in water management or industrial processes. The relationship between liters and cubic meters is that one cubic meter is equal to 1,000 liters. This conversion highlights the scalability of the metric system.
