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 721 kilometers per hour into feet per second we have to multiply 721 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

721 km/h → V_(ft/s)

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

V_(ft/s) = 721 km/h × 0.91134441528215 ft/s

V_(ft/s) = 657.07932341843 ft/s

The final result is:

721 km/h → 657.07932341843 ft/s

We conclude that 721 kilometers per hour is equivalent to 657.07932341843 feet per second:

721 kilometers per hour = 657.07932341843 feet per second
