A variant of the point, equal to 0.3759 mm, or 1/72 of a French Royal inch (27.07 mm), or about 1/68 inch. Didot points are used in Europe. This unit is named after the French printer François Ambroise Didot (1730 - 1804) who defined the "point-based" typographical measurement system.
The siriometer is a rarely used and an obsolete astronomical unit of length, defined to be equal to about one million astronomical units (au). One siriometer is approximately 149.6 petametres; 4.848 parsecs; 15.8 ..more definition+
