API, OpenAPI and WebMCP documentation

Explanation

Fathoms convert into nautical miles inside the marine distance family. Formula: nmi = ftm × 0.00098747300216. The same fixed relationship is used in the calculator, common values, and mirror page so route checks stay aligned.

This is useful for marine navigation, onboard operations, sounding work, or vessel-capacity checks where nautical units and engineering units need to line up without changing the underlying reference model.

Method & Marine Basis

  • Method basis: fixed nautical-distance definitions used in navigation and chart-distance work.
  • Applied factor: 1 Fathom = 0.000987 Nautical Miles.
  • Consistency rule: calculator output and common-value rows use the same fixed marine constants in both directions.
