Gigameter to Astronomical unit
Gigameter (Gm)
Astronomical unit (au)
How it is calculated
Each unit is defined via the base unit (meter (m)). The value is first converted to the base unit, then to the selected unit.
1 Gm = 1000000000 m
1 au = 149597870700 m
1 Gm × 1000000000 = 1000000000 m
1000000000 m ÷ 149597870700 = 0.00668458712227 au
