# Cubic centimetre

The **cubic metre** (symbol **m³**) is the SI derived unit of volume. It is the volume of a cube with edges one metre in length.

## History

Older equivalents were the **stere** and the **kilolitre**. The deprecation of the stere began in 1978, when the CIPM marked it (and several other metric units) as "undesirable" where not already in use, and strongly encouraged their discontinuation; in the United States, it was legally deprecated in 1982 (*Federal Register*, February 26, 1982, 47 FR 8399-8400) [1] [2].

## Conversions

1 cubic metre is equivalent to:

- 1,000 litres (exactly)
- ~35.3 cubic feet (approximately). 1 cubic foot is 0.028 316 846 592 m³ (exactly)
- ~1.31 cubic yards (approximately). 1 cubic yard is 0.764 554 857 984 m³ (exactly)
- ~6.29 oil barrels (approximately). 1 barrel is 0.158 987 294 928 m³ (exactly)

A cubic metre of pure water at a temperature of 3.98 °C (degrees Celsius) and standard atmospheric pressure has a mass of 999.972 kg (nearly one tonne).

It can either be abbreviated **m3** or **m^3** when superscript characters are not available/accessible (i.e. in some typewritten documents and postings in Usenet newsgroups).

**cubic decimetre**(symbol**dm³**) is the volume of a cube of side length 1 decimetre (0.1 metre).- 1 cubic decimetre is now equal to 1 litre. See 1 E-3 m³ for a comparison with other volumes.
- From 1901 to 1964 of the litre was defined as the volume of 1 kilogram of pure water at 4 degrees Celsius and 760 millimetres of mercury pressure. During this time, a litre was about 1.000028 dm³. In 1964 the original definition was reverted to.

- 1 cubic decimetre is now equal to 1 litre. See 1 E-3 m³ for a comparison with other volumes.

- A
**cubic centimetre**(**cm³**) is equal to the volume of a cube with side length of 1 centimetre. It was the base unit of volume of the CGS system of units, and is a legitimate SI unit.- The colloquial abbreviations
**cc**and**ccm**are not SI but are common in some contexts in English. For example 'cc' is commonly used for denoting displacement of car and motorbike engines "the Mini Cooper had a 1275 cc engine". In American medicine 'cc' is also common, for example "100 cc of blood loss".

- The colloquial abbreviations

- A cubic millimetre (mm³) is the volume equal to that of a cube with edges of 1 millimetre.

- A cubic kilometre (km³) is the volume equal to that of a cube of side length 1 kilometre.
