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 221.5 kilometers per hour into feet per second we have to multiply 221.5 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

221.5 km/h → V_(ft/s)

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

V_(ft/s) = 221.5 km/h × 0.91134441528215 ft/s

V_(ft/s) = 201.862787985 ft/s

The final result is:

221.5 km/h → 201.862787985 ft/s

We conclude that 221.5 kilometers per hour is equivalent to 201.862787985 feet per second:

221.5 kilometers per hour = 201.862787985 feet per second

Alternative conversion
