About the Typography Unit Converter
Typography uses specialised units to describe type size and layout with precision. The point (pt) has been the fundamental typographic unit since the 18th century; 72 points equal one inch in the modern DTP (desktop publishing) standard. The pica (12 points) is used for column widths and margins. Pixels (px) in CSS are device-independent units defined as 1/96 of an inch. Millimetres and centimetres are preferred in metric countries for print design specifications.
