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 425.7 kilometers per hour into feet per second we have to multiply 425.7 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

425.7 km/h → V_(ft/s)

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

V_(ft/s) = 425.7 km/h × 0.91134441528215 ft/s

V_(ft/s) = 387.95931758561 ft/s

The final result is:

425.7 km/h → 387.95931758561 ft/s

We conclude that 425.7 kilometers per hour is equivalent to 387.95931758561 feet per second:
