## 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 400 kilometers per hour into feet per second we have to multiply 400 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

400 km/h → V(ft/s)

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

V(ft/s) = 400 km/h × 0.91134441528215 ft/s

V(ft/s) = 364.53776611286 ft/s

The final result is:

400 km/h → 364.53776611286 ft/s

We conclude that 400 kilometers per hour is equivalent to 364.53776611286 feet per second:

400 kilometers per hour = 364.53776611286 feet per second ## Alternative conversion
