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 8420 kilometers per hour into feet per second we have to multiply 8420 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

8420 km/h → V_(ft/s)

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

V_(ft/s) = 8420 km/h × 0.91134441528215 ft/s

V_(ft/s) = 7673.5199766757 ft/s

The final result is:

8420 km/h → 7673.5199766757 ft/s

We conclude that 8420 kilometers per hour is equivalent to 7673.5199766757 feet per second:
