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 4640 kilometers per hour into feet per second we have to multiply 4640 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

4640 km/h → V_(ft/s)

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

V_(ft/s) = 4640 km/h × 0.91134441528215 ft/s

V_(ft/s) = 4228.6380869092 ft/s

The final result is:

4640 km/h → 4228.6380869092 ft/s

We conclude that 4640 kilometers per hour is equivalent to 4228.6380869092 feet per second:

4640 kilometers per hour = 4228.6380869092 feet per second
