SwitchExplanation
Formula: Nautical Miles = Kilometer × 0.539957. Why: marine distance units are normalized through nautical-mile definitions, then rescaled with fixed constants for cables, fathoms, meters, kilometers, and statute miles.
Kilometers (km): a metric distance unit equal to 1,000 meters, often used when marine values are compared with land-based metric references.
Nautical Miles (nmi): the standard marine distance unit used for navigation, charting, and route planning.
This route is useful when translating nautical track distances into chart, metric, or land-linked units for navigation, route planning, and marine reporting.
This conversion is purely multiplicative because both units reduce through one fixed marine reference basis for the active family, with no offset.
