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 921 kilometers per hour into feet per second we have to multiply 921 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

921 km/h → V_(ft/s)

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

V_(ft/s) = 921 km/h × 0.91134441528215 ft/s

V_(ft/s) = 839.34820647486 ft/s

The final result is:

921 km/h → 839.34820647486 ft/s

We conclude that 921 kilometers per hour is equivalent to 839.34820647486 feet per second:

921 kilometers per hour = 839.34820647486 feet per second
