Conversion formula

The conversion factor from kilometers per hour to feet per second is 0.91134441528215, which means that 1 kilometer per hour is equal to 0.91134441528215 feet per second:

1 km/h = 0.91134441528215 ft/s

To convert 21.2 kilometers per hour into feet per second we have to multiply 21.2 by the conversion factor in order to get the velocity amount from kilometers per hour to feet per second. We can also form a simple proportion to calculate the result:

1 km/h → 0.91134441528215 ft/s

21.2 km/h → V(ft/s)

Solve the above proportion to obtain the velocity V in feet per second:

V(ft/s) = 21.2 km/h × 0.91134441528215 ft/s

V(ft/s) = 19.320501603982 ft/s

The final result is:

21.2 km/h → 19.320501603982 ft/s

We conclude that 21.2 kilometers per hour is equivalent to 19.320501603982 feet per second:

21.2 kilometers per hour = 19.320501603982 feet per second
