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 120 miles per hour into feet per second we have to multiply 120 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

120 mph → V_(ft/s)

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

V_(ft/s) = 120 mph × 1.4666666666667 ft/s

V_(ft/s) = 176 ft/s

The final result is:

120 mph → 176 ft/s

We conclude that 120 miles per hour is equivalent to 176 feet per second:

120 miles per hour = 176 feet per second
