You can do the reverse unit conversion from decametres to astronomical unit, or enter any two units below:
The astronomical unit (AU or au or a.u. or sometimes ua) is a unit of length defined to be exactly equal to 149,597,870,700 metres. Historically, the astronomical unit was conceived as the average Earth-Sun distance (the average of Earth's aphelion and perihelion), before its modern redefinition.
The symbol "ua" is recommended by the Bureau International des Poids et Mesures, but in the United States and other anglophone countries the reverse usage is more common. The International Astronomical Union recommends "au" and international standard ISO 31-1 uses "AU".
A decametre (American spelling: dekameter, symbol: dam) is a measurement of distance equal to ten metres. This measure is included mostly for completeness. It very rarely has any practical application.
