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 671 kilometers per hour into feet per second we have to multiply 671 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

671 km/h → V_(ft/s)

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

V_(ft/s) = 671 km/h × 0.91134441528215 ft/s

V_(ft/s) = 611.51210265432 ft/s

The final result is:

671 km/h → 611.51210265432 ft/s

We conclude that 671 kilometers per hour is equivalent to 611.51210265432 feet per second:

671 kilometers per hour = 611.51210265432 feet per second
