Feet per second (ft/s) to Kilometers per hour (km/h) Conversion
Feet per second
Feet per second (ft/s) is a unit of speed in the US customary and imperial systems equal to approximately 0.3048 m/s or 1.09728 km/h. It is commonly used in ballistics to express projectile velocities, in structural engineering for wind speed calculations, and in sports science. The speed of sound at sea level is approximately 1,125 ft/s (343 m/s), a reference used in firearms and aeronautics.
Kilometers per hour
Kilometres per hour (km/h) is the standard unit for expressing speed in road transport, meteorology, and everyday life in all metric-system countries. Converting km/h to metres per second requires dividing by 3.6. Average human walking speed is approximately 5 km/h, highway speed limits range from 100 to 130 km/h, and commercial aircraft cruise at approximately 900 km/h.
