How to convert gigameters to nanometers
1 gigameter is equal to 1 × 10¹⁸ nanometers, and 1 nanometer is equal to 1 × 10⁻¹⁸ gigameters. To convert, multiply by the conversion factor:
nanometers = gigameters × 1 × 10¹⁸
nanometers = gigameters ÷ 1 × 10⁻¹⁸Example: convert 1 Gm to nm: 1 × 1 × 10¹⁸ = 1 × 10¹⁸ nm.

About the gigameter
A gigameter is one billion meters. The Moon orbits about 0.38 Gm from Earth, and the Sun's diameter is about 1.39 Gm.
Symbol: Gm · 1 Gm = 1,000,000,000 m · Category: Metric (SI)
About the nanometer
A nanometer is one billionth of a meter. It's used for wavelengths of light (visible light is about 380–750 nm), molecules and chip manufacturing processes.
Symbol: nm · 1 nm = 1 × 10⁻⁹ m · Category: Metric (SI)
