Convert Kilometers per Hour to Feet per Second

The km/h-to-ft/s conversion appears often when working with speed data across different unit systems. Speed conversions connect metric road limits, aviation knots, and imperial miles per hour — common when traveling internationally or reading foreign weather reports.

To convert, multiply the kilometers per hour value by 0.911345. Written as an equation: ft/s = km/h × 0.911345.

One kilometers per hour equals approximately 0.911345 ft/s. This means you can multiply any km/h value by 0.911345 to get the equivalent in ft/s.

Worked example: 25 km/h = 22.783629 ft/s. Enter your own value in the converter above for instant results.

Common mistake: Knots measure nautical miles per hour, not statute miles — they are close but not identical to mph.
