How to convert Astronomical unit to Gigameter

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

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 au = 149597870700 m

1 Gm = 1000000000 m

1 au × 149597870700 = 149597870700 m

149597870700 m ÷ 1000000000 = 149.5978707 Gm
