CSS Length Unit Table

Relative length units

cm Centimetres.
mm Millimetres.
pt Points (1 point = 1/72 inches).

Absolute or Relative

Measurements and positions in Cascading Style Sheets (CSS) properties are indicated in length units. Internet Explorer supports two types of length units: relative and absolute.

A relative length unit specifies a length in relation to another length property. Relative length units scale better from one output device to another, such as from a monitor to a printer.

An absolute length unit specifies an absolute measurement, such as inches or centimetres. Absolute length units are useful when the physical properties of the output device are known.
