FPS to MPH Converter
Convert between feet per second (FPS) and miles per hour (MPH) instantly. This calculator supports bidirectional conversion with high precision, perfect for physics problems, sports analytics, vehicle speed analysis, and ballistics calculations.
What Is FPS to MPH Conversion?
Feet per second (FPS) and miles per hour (MPH) are both units of speed or velocity. FPS is commonly used in physics, ballistics, and sports analytics, while MPH is the standard unit for vehicle speeds in the United States and several other countries.
1 FPS = 0.681818 MPH
1 MPH = 1.466667 FPS
The Conversion Formula
To convert from FPS to MPH, multiply the speed in feet per second by 0.681818 (or divide by 1.466667):
MPH = FPS × 0.681818
FPS = MPH × 1.466667
The conversion factor comes from the relationship between feet, miles, and seconds: 1 mile = 5,280 feet, and 1 hour = 3,600 seconds. Therefore, 1 FPS = (1/5280) miles per second = (3600/5280) miles per hour = 0.681818 MPH.

❓ FPS to MPH Converter FAQ
What is the formula to convert FPS to MPH?
To convert feet per second to miles per hour, multiply the FPS value by 0.681818. For example, 88 FPS × 0.681818 = 60 MPH. You can also use the shortcut: divide FPS by 1.466667.
What is 88 FPS in MPH?
88 feet per second is exactly 60 miles per hour. This is a helpful conversion to remember!
What is 1,100 FPS in MPH?
1,100 FPS is approximately 750 MPH. This is a common rifle muzzle velocity.
Why is 88 FPS equal to 60 MPH?
60 mph = 60 × 5,280 feet per hour = 316,800 feet per hour. Divide by 3,600 seconds per hour gives 88 feet per second. This exact relationship makes 88 fps the clean conversion point.
What is the difference between FPS and MPH?
FPS (feet per second) measures how many feet are traveled in one second. MPH (miles per hour) measures how many miles are traveled in one hour. MPH is commonly used for vehicle speeds, while FPS is used in physics, ballistics, and sports analytics.
How do I convert MPH to FPS?
To convert miles per hour to feet per second, multiply the MPH value by 1.466667. For example, 60 MPH × 1.466667 = 88 FPS.
What is the conversion factor between FPS and MPH?
1 FPS = 0.681818 MPH, and 1 MPH = 1.466667 FPS. These factors are derived from 1 mile = 5,280 feet and 1 hour = 3,600 seconds.
