Translate traditional marine depth units

Fathoms are a traditional marine depth unit still encountered on charts, historical records, and nautical writing. The international fathom is defined as six feet, which equals exactly 1.8288 meters. This converter changes that stated depth in either direction without interpreting chart context.

The default 10 fathoms converts to exactly 18.288 meters. Reversing direction converts 10 meters to 5.46807 fathoms. A charted depth may depend on a specified datum and current tide, but those conditions do not alter the underlying unit factor.

Private unit conversion, not navigation

Depth values stay in your browser and are not shared with a marine service. This page does not replace current charts, soundings, tide data, or safe-navigation procedures. It only converts a number already expressed in fathoms or meters.
