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 Thou (also called Mil) is essential in precision engineering and manufacturing. For context, a standard sheet of paper is about 100 thou thick, while human hair measures approximately 20-30 thou in diameter. This unit is critical in machining tolerances, PCB design, and automotive engineering where exact measurements are crucial.
To convert between Fathom (ftm) and Thou (Mil) (mil), use the following formulas:
1 Fathom (ftm) = 72000 Thou (Mil) (mil)
1 Thou (Mil) (mil) = 0.00001388888888888889 Fathom (ftm)
1 ftm = 1 * 72000 mil = 72000 mil
5 ftm = 5 * 72000 mil = 360000 mil
10 ftm = 10 * 72000 mil = 720000 mil
20 ftm = 20 * 72000 mil = 1440000 mil
50 ftm = 50 * 72000 mil = 3600000 mil
100 ftm = 100 * 72000 mil = 7200000 mil
| Fathom (ftm) | Thou (Mil) (mil) |
|---|---|
| 1 ftm | 72000 mil |
| 5 ftm | 360000 mil |
| 10 ftm | 720000 mil |
| 20 ftm | 1440000 mil |
| 50 ftm | 3600000 mil |
| 100 ftm | 7200000 mil |
