SwitchExplanation
Formula: Feet per Second = Kilometer per Hour × 0.911344. Why: marine speed units are normalized through knots, so the route follows one deterministic vessel-speed basis before applying the target unit.
Kilometers per Hour (km/h): a metric speed unit often used for vehicle and land-transport comparisons.
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.
