SwitchExplanation
Formula: Fathoms = Foot × 0.166667. Why: sounding and chart-depth units use fixed length definitions, so the calculator moves through one consistent depth basis before applying the target unit.
Feet (ft): an imperial length unit often used for sounding, draft, and depth reporting.
Fathoms (ftm): a marine length unit traditionally used for depth and sometimes short nautical distance references.
This route is useful when comparing sounding and draft-related values across meters, fathoms, feet, and yards in charting, surveying, and onboard operations.
This conversion is purely multiplicative because both units reduce through one fixed marine reference basis for the active family, with no offset.
