Marine & NauticalFeet per Second to Meters per Second

Feet per Second to Meters per Second

Snapshot

1 Foot per Second equals 0.3048 Meters per Second. Conversion Encyclopedia uses the same fixed conversion basis across the calculator, common values, and reverse page for this page.

Reference basis: This result uses fixed vessel-speed definitions anchored to knots and the active marine route.
Example: For 5 Feet per Second, the result equals 1.524 Meters per Second.
Use the reverse page if you need the opposite direction with the same basis.

Full API documentation

Explanation

Formula: Meters per Second = Foot per Second × 0.3048. Why: marine speed units are normalized through knots, so the route follows one deterministic vessel-speed basis before applying the target unit.

Feet per Second (ft/s): an imperial speed unit used in engineering and flow-style velocity references.

Meters per Second (m/s): an SI speed unit used in engineering, fluid, and motion calculations.

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.

Method & Marine Basis

Method basis: fixed vessel-speed definitions anchored to knots for marine reporting and instrumentation.
Applied factor: 1 Foot per Second = 0.3048 Meters per Second.
Consistency rule: calculator output and common-value rows use the same fixed marine constants in both directions.
