Astronomical scale (Moon's orbit = ~0.38 Gm). Useful for space agency data but rarely searched by the public. 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 Gigameter (Gm) and Decameter (dam), use the following formulas:
1 Gigameter (Gm) = 100000000 Decameter (dam)
1 Decameter (dam) = 1e-8 Gigameter (Gm)
0.15 Gm = 0.15 * 100000000 dam = 15000000 dam
1.5 Gm = 1.5 * 100000000 dam = 150000000 dam
4 Gm = 4 * 100000000 dam = 400000000 dam
| Gigameter (Gm) | Decameter (dam) |
|---|---|
| 0.1 Gm | 10000000 dam |
| 1 Gm | 100000000 dam |
| 10 Gm | 1000000000 dam |
| 100 Gm | 10000000000 dam |
