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 321 kilometers per hour into feet per second we have to multiply 321 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

321 km/h → V_(ft/s)

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

V_(ft/s) = 321 km/h × 0.91134441528215 ft/s

V_(ft/s) = 292.54155730557 ft/s

The final result is:

321 km/h → 292.54155730557 ft/s

We conclude that 321 kilometers per hour is equivalent to 292.54155730557 feet per second:

321 kilometers per hour = 292.54155730557 feet per second
