Conversion formula

The conversion factor from miles per hour to feet per second is 1.4666666666667, which means that 1 mile per hour is equal to 1.4666666666667 feet per second:

1 mph = 1.4666666666667 ft/s

To convert 1125 miles per hour into feet per second we have to multiply 1125 by the conversion factor in order to get the velocity amount from miles per hour to feet per second. We can also form a simple proportion to calculate the result:

1 mph → 1.4666666666667 ft/s

1125 mph → V_(ft/s)

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

V_(ft/s) = 1125 mph × 1.4666666666667 ft/s

V_(ft/s) = 1650 ft/s

The final result is:

1125 mph → 1650 ft/s
