Example
Enter 88 in the Feet per Second field. The tool calculates 88 ÷ 1.46667 = 60, so 88 ft/s equals exactly 60 mph.
Frequently Asked Questions
How fast is 88 ft/s in mph?
88 ft/s = 60 mph.
Where does the number 1.46667 come from?
It's the ratio of feet per second to miles per hour. One mile is 5,280 feet and one hour is 3,600 seconds, so 1 mph equals 5,280 ÷ 3,600 ≈ 1.46667 ft/s. Dividing any speed in feet per second by that figure converts it to miles per hour.
How fast is a thrown or batted baseball in mph from ft/s?
Radar guns often report exit velocity in mph directly, but underlying physics calculations use feet per second. A hard-hit baseball leaving the bat at about 160 ft/s converts to roughly 109 mph (160 ÷ 1.46667). A typical major-league fastball around 140 ft/s comes out to about 95 mph.
