The Fathom remains vital in maritime navigation, measuring water depth and anchor chains. One fathom equals 6 feet. For reference, recreational scuba divers typically explore depths of 10-20 fathoms (60-120 feet), while the Titanic rests at about 1,200 fathoms (7,200 feet) below sea level. 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.
To convert between Fathom (ftm) and Nautical Mile (nmi), use the following formulas:
1 Fathom (ftm) = 0.0009874730021598272 Nautical Mile (nmi)
1 Nautical Mile (nmi) = 1012.6859142607174 Fathom (ftm)
1 ftm = 1 * 0.0009874730021598272 nmi = 0.0009874730021598272 nmi
5 ftm = 5 * 0.0009874730021598272 nmi = 0.004937365010799136 nmi
10 ftm = 10 * 0.0009874730021598272 nmi = 0.009874730021598272 nmi
20 ftm = 20 * 0.0009874730021598272 nmi = 0.019749460043196543 nmi
50 ftm = 50 * 0.0009874730021598272 nmi = 0.049373650107991364 nmi
100 ftm = 100 * 0.0009874730021598272 nmi = 0.09874730021598273 nmi
