1 mph → 1.4666666666667 ft/s

503 mph → V_(ft/s)

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

V_(ft/s) = 503 mph × 1.4666666666667 ft/s

V_(ft/s) = 737.73333333333 ft/s

The final result is:

503 mph → 737.73333333333 ft/s

We conclude that 503 miles per hour is equivalent to 737.73333333333 feet per second:
