Class 8 Maths- Standard units of volume

Standard units of volume

Standard units: A unit which is acceptable to a majority of the people as a basic unit of measurement is called a standard unit.

For example: Length - meter or metre (m), Mass - kilogram (kg), Time - second (s), Current - ampere (A),  Temperature - Kelvin (K),   Amount of substance - mole (mol),   Luminous intensity - candela (cd)

A standard unit is called SI unit, which stands for International System of Units.

Any unit of length gives a corresponding unit of volume, namely the volume of a cube whose side has the given length. For example, a cubic centimetre (cm³) would be the volume of a cube whose sides are one centimetre (1 cm) in length.

In SI unit, the standard unit of volume is the cubic metre (m³). The metric system also includes the litre (L) as a unit of volume, where one litre is the volume of a 10-centimetre cube.

Thus, 1 litre = (10 cm)³ = 1000 cubic centimetres = 0.001 cubic metres
