|---|---|---|
| 1.0 m | 0.547 fth | 1 m |
| 10 m | 5.47 fth | 10 m |
| 100 m | 54.68 fth | 100 m |
| 1,000 m | 546.81 fth | 1000 m |
Practical guidance
Historical navigation
Old charts and logs use fathoms. Converting from metric depth soundings helps you follow historical routes and understand vintage navigation records.
Communication with mixed fleets
When sailing with vessels from different regions, converting depths ensures everyone understands the seabed conditions.
Mistake: dividing by 2
Dividing by 2 gives 10 fathoms for 20 m instead of 10.94. Use 0.546807 for accuracy.
