}Explanation
Miles per Hour convert into knots inside the marine speed family. Formula: kn = mph × 0.868976241901. 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.
