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 521 kilometers per hour into feet per second we have to multiply 521 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

521 km/h → V_(ft/s)

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

V_(ft/s) = 521 km/h × 0.91134441528215 ft/s

V_(ft/s) = 474.810440362 ft/s

The final result is:

521 km/h → 474.810440362 ft/s

We conclude that 521 kilometers per hour is equivalent to 474.810440362 feet per second:

521 kilometers per hour = 474.810440362 feet per second
