Absolute-length measurements:
- pt (point(s); 1 pt = 1/72 inch)
- pc (pica(s); 1 pc = 12 pt)
- mm (millimeters)

- The relation between these units is: 1in = 2.54cm = 25.4mm = 72pt = 6pc
Relative length measurements:
- em (generally the height of a font's uppercase M)
- px (pixel but size depends on screen resolution)
