Enter the speed in feet per second into the calculator to determine the speed in miles per hour. This calculator can also evaluate any of the variables given the others are known.

Feet To Mph Formula

The following formula is used to calculate speed in miles per hour from feet per second.

MPH = FT/S * 0.681818

Variables:

  • MPH is the speed in miles per hour
  • FT/S is the speed in feet per second 0.681818 is the conversion factor from feet per second to miles per hour

To calculate the speed in miles per hour, multiply the speed in feet per second by the conversion factor 0.681818.

What is Feet To Mph?

Feet to Mph (Miles per Hour) is a conversion factor used to convert a speed or velocity measurement from feet per second (ft/s) to miles per hour (mph). This is commonly used in physics and engineering to express the speed of an object or vehicle in different units. The conversion factor is approximately 0.681818, meaning that to convert from feet per second to miles per hour, you multiply the speed in ft/s by 0.681818.

How to Calculate Feet To Mph?

The following steps outline how to calculate the Feet To Mph using the given formula.


  1. First, determine the speed in feet per second (FT/S).
  2. Next, insert the value of FT/S into the formula: MPH = FT/S * 0.681818.
  3. Finally, calculate the speed in miles per hour (MPH).
  4. After inserting the variables and calculating the result, check your answer with the calculator above.
