Astronomical scale (Moon's orbit = ~0.38 Gm). Useful for space agency data but rarely searched by the public. Used in planetary science (Earth's diameter = ~12.7 Mm). Also for long-distance fiber optics or satellite measurements.
To convert between Gigameter (Gm) and Megameter (Mm), use the following formulas:
1 Gigameter (Gm) = 1000 Megameter (Mm)
1 Megameter (Mm) = 0.001 Gigameter (Gm)
0.15 Gm = 0.15 * 1000 Mm = 150 Mm
1.5 Gm = 1.5 * 1000 Mm = 1500 Mm
4 Gm = 4 * 1000 Mm = 4000 Mm
| Gigameter (Gm) | Megameter (Mm) |
|---|---|
| 0.1 Gm | 100 Mm |
| 1 Gm | 1000 Mm |
| 10 Gm | 10000 Mm |
| 100 Gm | 100000 Mm |
