Used in planetary science (Earth's diameter = ~12.7 Mm). Also for long-distance fiber optics or satellite measurements. The decameter (dam) is used to measure medium-scale distances like the length of a tennis court (~2.3 dam) or a cricket pitch (~2.0 dam). It’s also practical for land surveying and agricultural plots (e.g., a small field might be 10 dam × 20 dam).
To convert between Megameter (Mm) and Decameter (dam), use the following formulas:
1 Megameter (Mm) = 100000 Decameter (dam)
1 Decameter (dam) = 0.00001 Megameter (Mm)
1 Mm = 1 * 100000 dam = 100000 dam
2.4 Mm = 2.4 * 100000 dam = 240000 dam
5 Mm = 5 * 100000 dam = 500000 dam
10 Mm = 10 * 100000 dam = 1000000 dam
| Megameter (Mm) | Decameter (dam) |
|---|---|
| 1 Mm | 100000 dam |
| 5 Mm | 500000 dam |
| 10 Mm | 1000000 dam |
| 50 Mm | 5000000 dam |
| 100 Mm | 10000000 dam |
