Convert megameter to gigameter
Enter a value below to convert megameter [Mm] to gigameter [Gm]. Reverse conversion: Convert gigameter to megameter.
1 Mm = 0.001 Gm. To convert megameter to gigameter, multiply the value by 0.001; to go the other way, divide by it (1 Gm = 1000 Mm). Both units measure length and appear in everyday as well as technical calculations, so switching between them quickly is often useful.

Megameter: Definition and Use
A megameter is a unit of length in the metric system equal to 10^6 meters.
History/Origin
The prefix "mega-" for 10^6 was adopted by the CGPM (General Conference on Weights and Measures) in 1873.
Current Use
The megameter is sometimes used to specify the diameters of planets and the distances of satellites.
Gigameter: Definition and Use
A gigameter is a unit of length in the metric system equal to 10^9 meters.
History/Origin
The prefix "giga-" for 10^9 was adopted by the CGPM (General Conference on Weights and Measures) in 1960.
Current Use
The gigameter is used for measuring interplanetary distances, for example, the distance between Earth and Mars.
