How to convert feet per second to kilometers per hour
1 ft/s = 1.09728 km/h, so multiply by 1.09728 to go from feet per second to kilometers per hour. Going the other way, 1 km/h = 0.911344415281 ft/s.
km/h = ft/s × 1.09728 ft/s = km/h × 0.911344415281
Worked example:
1 ft/s = 1.09728 km/h 5 × 1.09728 = 5.4864 km/h
