Feet per second to km/h – convert fps to km/h

Convert feet per second to kilometres per hour (fps to km/h) to compare impact speeds, ball speeds and experimental data with everyday vehicle and running speeds.

Open the interactive fps → km/h converter:

Use main converter (fps → km/h) or switch to km/h → fps

The speed converter also supports m/s, km/h, mph and knots for land, air and marine speeds.

Quick reference: fps to km/h

One foot per second is about 1.097 km/h. So: km/h = fps × 1.09728. Examples:

Feet per second (fps) Speed (km/h, approx.)
5 fps5.49 km/h
10 fps10.97 km/h
20 fps21.95 km/h
30 fps32.92 km/h
50 fps54.86 km/h
100 fps109.73 km/h
