1686 km/h → V_(ft/s)

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

V_(ft/s) = 1686 km/h × 0.91134441528215 ft/s

V_(ft/s) = 1536.5266841657 ft/s

The final result is:

1686 km/h → 1536.5266841657 ft/s

We conclude that 1686 kilometers per hour is equivalent to 1536.5266841657 feet per second:
