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. 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.
To convert between Rod (rd) and Fathom (ftm), use the following formulas:
1 Rod (rd) = 2.75 Fathom (ftm)
1 Fathom (ftm) = 0.3636363636363636 Rod (rd)
1 rd = 1 * 2.75 ftm = 2.75 ftm
2 rd = 2 * 2.75 ftm = 5.5 ftm
5 rd = 5 * 2.75 ftm = 13.75 ftm
10 rd = 10 * 2.75 ftm = 27.5 ftm
20 rd = 20 * 2.75 ftm = 55 ftm
50 rd = 50 * 2.75 ftm = 137.5 ftm
| Rod (rd) | Fathom (ftm) |
|---|---|
| 1 rd | 2.75 ftm |
| 2 rd | 5.5 ftm |
| 5 rd | 13.75 ftm |
| 10 rd | 27.5 ftm |
| 20 rd | 55 ftm |
| 50 rd | 137.5 ftm |
