Miles per Hour to Feet per Second Converter
1 Mile per Hour = 1.466666667 Feet per Second
The mile per hour and the foot per second are both essential units in velocity measurement. Feet per second is part of the Imperial/US customary system and is commonly used in ballistics, engineering, and some areas of physics. Since 1 mph equals 1.46667 ft/s, understanding this relationship is valuable for anyone working in aviation or meteorology.
Did you know? Did you know? The mile per hour is commonly used for vehicle speed in the US/UK, baseball pitch speed, and hurricane wind speed. A bullet from a rifle travels at about 2,500 feet per second - and knowing the conversion between these two units makes working across measurement systems effortless.

About Miles per Hour to Feet per Second
The mile per hour-to-foot per second conversion is widely used across velocity measurement. Miles per hour became common in the US and UK with the advent of automobiles in the early 20th century. It is still the standard for road speeds in those countries. The foot per second has its own rich history: feet per second is part of the imperial/us customary system and is commonly used in ballistics, engineering, and some areas of physics. Understanding both units and how they relate to each other is essential for professionals in transportation, athletics, and aviation.
In practice, this conversion comes up frequently when comparing speed limits across countries. For example, 1 mph = 1.46667 ft/s, 10 mph = 14.6667 ft/s, and 100 mph = 146.667 ft/s. The fastest recorded baseball pitch was 105.1 miles per hour. Similarly, a bullet from a rifle travels at about 2,500 feet per second. Having an instant converter saves time and eliminates the risk of manual calculation errors, especially when precision matters.
To convert back from feet per second to miles per hour, remember that 1 ft/s = 0.681818 mph. The mile per hour is primarily used for vehicle speed in the US/UK, baseball pitch speed, and hurricane wind speed, while the foot per second is the preferred unit for bullet velocity, elevator speed, and engineering calculations in the US. Whether you need a quick estimate or a precise figure, our converter handles both - simply enter any value and get an instant, accurate result with the full conversion formula.
