The Nautical Mile is used for global navigation, equaling one minute of latitude (about 1.15 statute miles). Commercial airliners cruise at altitudes of 35,000-40,000 feet (about 6 nautical miles). Modern nautical charts still use this measurement, and international maritime law specifies territorial waters in nautical miles. 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 Nautical Mile (nmi) and Decameter (dam), use the following formulas:
1 Nautical Mile (nmi) = 185.2 Decameter (dam)
1 Decameter (dam) = 0.005399568034557235 Nautical Mile (nmi)
1 nmi = 1 * 185.2 dam = 185.2 dam
5 nmi = 5 * 185.2 dam = 926 dam
10 nmi = 10 * 185.2 dam = 1852 dam
20 nmi = 20 * 185.2 dam = 3704 dam
50 nmi = 50 * 185.2 dam = 9260 dam
100 nmi = 100 * 185.2 dam = 18520 dam
