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 815 kilometers per hour into feet per second we have to multiply 815 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

815 km/h → V_(ft/s)

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

V_(ft/s) = 815 km/h × 0.91134441528215 ft/s

V_(ft/s) = 742.74569845495 ft/s

The final result is:

815 km/h → 742.74569845495 ft/s

We conclude that 815 kilometers per hour is equivalent to 742.74569845495 feet per second:

815 kilometers per hour = 742.74569845495 feet per second
