How to convert Gigameter to Astronomical unit

Conversion factor and calculation steps from Gigameter (Gm) to Astronomical unit (au).

Conversion logic

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
