What is the formula for converting velocity to Feet Per Second?

The formula for converting miles per hour (MPH) to feet per second (FPS) involves utilizing the conversion factor that relates these two units of measurement. To convert MPH to FPS, you multiply the speed in miles per hour by approximately 1.47. This value comes from the fact that there are 5280 feet in a mile and 3600 seconds in an hour, leading to the following mathematical relationship:

1 MPH = 5280 feet / 3600 seconds ≈ 1.47 FPS.

Therefore, by multiplying a speed measured in miles per hour by 1.47, you accurately convert that speed into feet per second. This understanding is fundamental in various applications, such as law enforcement scenarios where precise speed measurement may be necessary for enforcement actions and reporting.
