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 5421 kilometers per hour into feet per second we have to multiply 5421 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

5421 km/h → V_(ft/s)

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

V_(ft/s) = 5421 km/h × 0.91134441528215 ft/s

V_(ft/s) = 4940.3980752445 ft/s

The final result is:

5421 km/h → 4940.3980752445 ft/s

We conclude that 5421 kilometers per hour is equivalent to 4940.3980752445 feet per second:
