How to convert Gigameter to Nanometer

Conversion factor and calculation steps from Gigameter (Gm) to Nanometer (nm).

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 nm = 1.00000000e-9 m

1 Gm × 1000000000 = 1000000000 m

1000000000 m ÷ 1.00000000e-9 = 1.00000000e18 nm
