Astronomical Unit (AU, UA) is a unit in the category of Length. It is also known as au. Astronomical Unit (AU, UA) has a dimension of L where L is length. It can be converted to the corresponding standard SI unit m by multiplying its value by a factor of 149597870000.
Note that the seven base dimensions are M (Mass), L (Length), T (Time), Q (Temperature), N (Aamount of Substance), I (Electric Current), and J (Luminous Intensity).
