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 666 kilometers per hour into feet per second we have to multiply 666 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

666 km/h → V_(ft/s)

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

V_(ft/s) = 666 km/h × 0.91134441528215 ft/s

V_(ft/s) = 606.95538057791 ft/s

The final result is:

666 km/h → 606.95538057791 ft/s

We conclude that 666 kilometers per hour is equivalent to 606.95538057791 feet per second:

666 kilometers per hour = 606.95538057791 feet per second
