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 1685 kilometers per hour into feet per second we have to multiply 1685 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

1685 km/h → V_(ft/s)

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

V_(ft/s) = 1685 km/h × 0.91134441528215 ft/s

V_(ft/s) = 1535.6153397504 ft/s

The final result is:

1685 km/h → 1535.6153397504 ft/s

We conclude that 1685 kilometers per hour is equivalent to 1535.6153397504 feet per second:
