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 6420 kilometers per hour into feet per second we have to multiply 6420 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

6420 km/h → V_(ft/s)

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

V_(ft/s) = 6420 km/h × 0.91134441528215 ft/s

V_(ft/s) = 5850.8311461114 ft/s

The final result is:

6420 km/h → 5850.8311461114 ft/s

We conclude that 6420 kilometers per hour is equivalent to 5850.8311461114 feet per second:

6420 kilometers per hour = 5850.8311461114 feet per second
