| 1.0 fth | 1.83 m | 1 fth |
| 5.0 fth | 9.14 m | 5 fth |
| 10 fth | 18.29 m | 10 fth |
| 20 fth | 36.58 m | 20 fth |
Practical guidance
Anchoring and mooring
Anchor chains and rode lengths are often specified in fathoms. Converting to meters ensures your ground tackle is adequate for the depth.
Marine surveys
Hydrographic charts may use fathoms for depth. Converting ensures divers and submersibles operate within safe limits.
Mistake: using 2 meters
A fathom is 1.83 m, not 2 m. Using 2 m overestimates depth by 9.4%. For 20 fathoms, the error is 3.4 m. Use 1.8288.
