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 4021 kilometers per hour into feet per second we have to multiply 4021 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

4021 km/h → V_(ft/s)

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

V_(ft/s) = 4021 km/h × 0.91134441528215 ft/s

V_(ft/s) = 3664.5158938495 ft/s

The final result is:

4021 km/h → 3664.5158938495 ft/s

We conclude that 4021 kilometers per hour is equivalent to 3664.5158938495 feet per second:

4021 kilometers per hour = 3664.5158938495 feet per second
