The astronomical unit (symbol au, or ua) is a unit of length, roughly the distance from Earth to the Sun. However, that distance varies as Earth orbits the Sun, f ..more definition+
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.
In relation to the base unit of [length] => (meters), 1 Astronomical Unit (au) is equal to 149597870700 meters, while 1 Didot Points (didot point) = 0.000375972222 meters.390000 Astronomical Unit | to common length units |
