What is the formula for converting velocity to feet per second?

The formula for converting miles per hour (mph) to feet per second (fps) is based on the relationship between these two units of measurement. Since one mile is equal to 5,280 feet and there are 3,600 seconds in an hour, the conversion factor can be derived.

To convert mph to fps, you can multiply by the factor of 5280 feet per mile divided by 3600 seconds per hour. This simplifies to approximately 1.46667. Thus, multiplying mph by about 1.47 provides a quick and convenient way to convert the speed from miles per hour to feet per second.

Given this understanding, when you choose to multiply the speed in mph by 1.47, you accurately convert that velocity into feet per second. It's important to know this conversion for various applications, particularly in fields where precise measurements of speed are essential, such as in vehicle operation and safety assessments.
