Used in planetary science (Earth's diameter = ~12.7 Mm). Also for long-distance fiber optics or satellite measurements. The hectometer (hm) is useful for measuring sports tracks (1 lap = 4 hm), urban blocks (~1–2 hm long), or vineyard rows. Road signs in some European countries use hectometers for minor distance markers.
To convert between Megameter (Mm) and Hectometer (hm), use the following formulas:
1 Megameter (Mm) = 10000 Hectometer (hm)
1 Hectometer (hm) = 0.0001 Megameter (Mm)
1 Mm = 1 * 10000 hm = 10000 hm
2.4 Mm = 2.4 * 10000 hm = 24000 hm
5 Mm = 5 * 10000 hm = 50000 hm
10 Mm = 10 * 10000 hm = 100000 hm
| Megameter (Mm) | Hectometer (hm) |
|---|---|
| 1 Mm | 10000 hm |
| 5 Mm | 50000 hm |
| 10 Mm | 100000 hm |
| 50 Mm | 500000 hm |
| 100 Mm | 1000000 hm |
