The astronomical unit of length is that length for which the Gaussian gravitational constant (k) takes the value 6998172020989500000â 0.01720209895 when the units of measurement are the astronomical units of length, mass and time. The dimensions of k 2 are those of the constant of gravitation (G), i.e., L 3 M â1 T â2. The term âunit distanceâ is also used for the length A while, in general usage, it is usually referred to simply as the âastronomical unitâ, symbol au, AU or ua.
