Used in planetary science (Earth's diameter = ~12.7 Mm). Also for long-distance fiber optics or satellite measurements. Astronomical scale (Moon's orbit = ~0.38 Gm). Useful for space agency data but rarely searched by the public.
To convert between Megameter (Mm) and Gigameter (Gm), use the following formulas:
1 Megameter (Mm) = 0.001 Gigameter (Gm)
1 Gigameter (Gm) = 1000 Megameter (Mm)
1 Mm = 1 * 0.001 Gm = 0.001 Gm
2.4 Mm = 2.4 * 0.001 Gm = 0.0024 Gm
5 Mm = 5 * 0.001 Gm = 0.005 Gm
10 Mm = 10 * 0.001 Gm = 0.01 Gm
| Megameter (Mm) | Gigameter (Gm) |
|---|---|
| 1 Mm | 0.001 Gm |
| 5 Mm | 0.005 Gm |
| 10 Mm | 0.01 Gm |
| 50 Mm | 0.05 Gm |
| 100 Mm | 0.1 Gm |
