Gigameter to Kilometer Converter (Gm to km)

How to convert gigameters to kilometers

1 gigameter is equal to 1,000,000 kilometers, and 1 kilometer is equal to 0.000001 gigameters. To convert, multiply by the conversion factor:

kilometers = gigameters × 1,000,000
kilometers = gigameters ÷ 0.000001

Example: convert 1 Gm to km: 1 × 1,000,000 = 1,000,000 km.

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)

A kilometer is 1,000 meters. It's the standard unit for distances between places, road signs and running races in most countries.

Symbol: km · 1 km = 1,000 m · Category: Metric (SI)
