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 437.9 kilometers per hour into feet per second we have to multiply 437.9 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

437.9 km/h → V_(ft/s)

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

V_(ft/s) = 437.9 km/h × 0.91134441528215 ft/s

V_(ft/s) = 399.07771945205 ft/s

The final result is:

437.9 km/h → 399.07771945205 ft/s

We conclude that 437.9 kilometers per hour is equivalent to 399.07771945205 feet per second:
