To convert Ramsden chains to fathoms, multiply the value by 16.6667. To go the other way, multiply fathoms by 0.06 to get Ramsden chains.
| Ramsden Chains (rch) | Fathoms (ftm) |
|---|---|
| 1 rch | 16.6667 ftm |
| 2 rch | 33.3333 ftm |
| 5 rch | 83.3333 ftm |
| 10 rch | 166.667 ftm |
| 20 rch | 333.333 ftm |
| 50 rch | 833.333 ftm |
| 100 rch | 1,666.67 ftm |
| 500 rch | 8,333.33 ftm |
| 1,000 rch | 16,666.7 ftm |
Ramsden chain (rch). The Ramsden or engineer's chain is 100 feet (30.48 m), used in engineering surveys.
Fathom (ftm). A fathom is 6 feet (1.8288 m), traditionally used to measure the depth of water.
There are 16.6667 fathoms in one Ramsden chain.
Multiply the number of Ramsden chains by 16.6667. For example, 10 Ramsden chains equal 166.667 fathoms.
One fathom equals 0.06 Ramsden chains.
