Definition

Various metric units of volume which have specific names are as follows:

Cubic Centimetre

The cubic centimetre is the CGS unit of volume.

It is defined as the volume contained by a cube whose edges are $1$ centimetre long.

\(\ds \) \(\) \(\ds 1\) cubic centimetre
\(\ds \) \(=\) \(\ds 1\) millilitre
\(\ds \) \(=\) \(\ds 10^{-3}\) litre


Cubic Metre

The cubic metre is the SI unit of volume.


The symbol for the cubic metre is $\mathrm m^3$.


Microlitre

The microlitre is an SI unit of volume.

\(\ds \) \(\) \(\ds 1\) microlitre
\(\ds \) \(=\) \(\ds 10^{-3}\) millilitre
\(\ds \) \(=\) \(\ds 10^{-6}\) litre


Millilitre

The millilitre is a unit of volume.

It is the same as a cubic centimetre, which is the equivalent SI unit.

\(\ds \) \(\) \(\ds 1\) millilitre
\(\ds \) \(=\) \(\ds 1000\) microlitres
\(\ds \) \(=\) \(\ds 1\) cubic centimetre
\(\ds \) \(=\) \(\ds 10^{-3}\) litre


Litre

The litre is a unit of volume based on, but not actually part of, the SI system.

\(\ds \) \(\) \(\ds 1\) litre
\(\ds \) \(=\) \(\ds 1000\) millilitres
\(\ds \) \(=\) \(\ds 1000\) cubic centimetres
\(\ds \) \(=\) \(\ds 10^{-3}\) cubic metres
\(\ds \) \(\approx\) \(\ds 1 \cdotp 76\) pints
