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 Rod (or pole/perch) was historically used in land surveying and agriculture. Measuring exactly 16.5 feet, rods were commonly used to define property boundaries. A standard American football field is 320 rods long (including end zones). This unit still appears in some property deeds and agricultural measurements.
To convert between Fathom (ftm) and Rod (rd), use the following formulas:
1 Fathom (ftm) = 0.3636363636363636 Rod (rd)
1 Rod (rd) = 2.75 Fathom (ftm)
1 ftm = 1 * 0.3636363636363636 rd = 0.3636363636363636 rd
5 ftm = 5 * 0.3636363636363636 rd = 1.818181818181818 rd
10 ftm = 10 * 0.3636363636363636 rd = 3.636363636363636 rd
20 ftm = 20 * 0.3636363636363636 rd = 7.272727272727272 rd
50 ftm = 50 * 0.3636363636363636 rd = 18.18181818181818 rd
100 ftm = 100 * 0.3636363636363636 rd = 36.36363636363636 rd
