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 kilometers per hour into feet per second we have to multiply 425 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 km/h → V_(ft/s)

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

V_(ft/s) = 425 km/h × 0.91134441528215 ft/s

V_(ft/s) = 387.32137649491 ft/s

The final result is:

425 km/h → 387.32137649491 ft/s

We conclude that 425 kilometers per hour is equivalent to 387.32137649491 feet per second:

425 kilometers per hour = 387.32137649491 feet per second
