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 142.6 kilometers per hour into feet per second we have to multiply 142.6 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

142.6 km/h → V_(ft/s)

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

V_(ft/s) = 142.6 km/h × 0.91134441528215 ft/s

V_(ft/s) = 129.95771361923 ft/s

The final result is:

142.6 km/h → 129.95771361923 ft/s

We conclude that 142.6 kilometers per hour is equivalent to 129.95771361923 feet per second:

142.6 kilometers per hour = 129.95771361923 feet per second
