SwitchExplanation
Formula: Feet per Second = Mile per Hour × 1.466667. Why: marine speed units are normalized through knots, so the route follows one deterministic vessel-speed basis before applying the target unit.
Miles per Hour (mph): a common land-speed unit used when vessel or current speeds are restated in statute terms.
Feet per Second (ft/s): an imperial speed unit used in engineering and flow-style velocity references.
This route is useful when restating vessel speed between knots and engineering or land-speed units for navigation, instrumentation, and performance reporting.
This conversion is purely multiplicative because both units reduce through one fixed marine reference basis for the active family, with no offset.
