What this calculator does
Converts a measurement given in kilometre per hours into foot per seconds using the defined conversion factor.
What your result means
The same quantity expressed in ft/s instead of km/h. Nothing about the measurement itself changes.
Formula and working
ft/s = km/h × 0.9113444153

Frequently asked questions
Symbols and assumptions
- km/h
- Input unit — kilometre per hour
- ft/s
- Output unit — foot per second
- m/s
- Base unit used internally for speed and velocity
- • Both units measure speed and velocity, so the physical quantity is unchanged by the conversion.
- • The relationship is exactly linear: 1 km/h = 0.9113444153 ft/s.
- • Values are converted through the SI base unit for this quantity rather than pair by pair.

- • A unit conversion changes how a number is expressed, not how it was measured — the answer can never be more accurate than the value entered.
- • Displayed figures are rounded for readability; the full stored precision of the ft/s value is used in every onward calculation.
