Metric typographic units have been devised and proposed several times to overcome the various traditional point systems. After the French revolution of 1789 one popular proponent of a switch to metric was Didot, who had been able to standardise the continental European typographic measurement a few decades earlier. The conversion did not happen, though. The Didot point was metrically redefined as 1⁄2660 m (≈ 0.376 mm) in 1879 by Berthold.

The advent and success of desktop publishing (DTP) software and word processors for office use, coming mostly from the non-metric United States, basically revoked this metrication process in typography. DTP commonly uses the PostScript point, which is defined as 1⁄72 of an inch (352.(7) μm).
