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 4200 kilometers per hour into feet per second we have to multiply 4200 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

4200 km/h → V_(ft/s)

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

V_(ft/s) = 4200 km/h × 0.91134441528215 ft/s

V_(ft/s) = 3827.646544185 ft/s

The final result is:

4200 km/h → 3827.646544185 ft/s

We conclude that 4200 kilometers per hour is equivalent to 3827.646544185 feet per second:

4200 kilometers per hour = 3827.646544185 feet per second
