The kilometer per hour
The kilometer per hour (km/h) is the standard speed unit on road signs almost everywhere except the United States and the United Kingdom. To convert to meters per second, divide by 3.6 (since 1 km = 1000 m and 1 h = 3600 s).
Kilometers per hour to Feet per second
1 km/h = 0.911344 ft/s (kilometer per hour → foot per second)
1 km/h = 0.911344 ft/s
1 kilometer per hour equals 0.911344 feet per second. To convert kilometers per hour to feet per second, multiply the kilometer per hour value by 0.911344. For quick reference: 1 km/h = 0.911344 ft/s, 5 km/h = 4.55672 ft/s, 10 km/h = 9.11344 ft/s, 100 km/h = 91.1344 ft/s.
Formula
Feet per second = Kilometers per hour × 0.911344Quick

About the kilometer per hour and the foot per second
The foot per second
The foot per second (ft/s, fps) equals exactly 0.3048 m/s. It is common in US ballistics (muzzle velocity), engineering (fluid flow, elevator speed), and physics classrooms as an imperial alternative to mph.
