The Miles per Hour to Feet per Second Converter converts speed from mph to ft/s using the factor 1 mph = 1.46667 ft/s (exactly 22/15). This conversion is used in vehicle stopping distance calculations, sports analysis, ballistics comparison, and physics education.
Understanding mph in ft/s terms provides a more intuitive grasp of how far a vehicle travels each second. At 60 mph, you travel 88 feet every second — that's about 6 car lengths. This perspective is valuable for understanding reaction distances and braking distances in driver safety education.
The famous benchmark: 60 mph = 88 ft/s. For every 10 mph increase, speed increases by about 14.67 ft/s. At highway speeds (70 mph = 102.67 ft/s), a 1-second distraction means traveling over 100 feet blind.
Results also include m/s for scientific applications.
The formula: ft/s = mph × 5280/3600 = mph × 22/15 ≈ mph × 1.46667. The fraction 22/15 is exact. For m/s: m/s = mph × 0.44704 (exact). The conversion from mph to ft/s is based on 1 mile = 5280 ft and 1 hour = 3600 seconds.
Driver safety: at 30 mph (44 ft/s), a 1-second reaction covers 44 ft. At 60 mph (88 ft/s), the same reaction covers 88 ft. Braking distance adds more: total stopping distance at 60 mph ≈ 240 ft (4 car lengths for reaction + braking).

60 mph = exactly 88 ft/s.
Multiply mph by 1.46667 (or 22/15). For a quick estimate, multiply by 1.5 and subtract a bit.
It shows how far you travel each second. At 60 mph (88 ft/s), a 2-second distraction means 176 feet traveled without watching the road.
100 mph = 146.67 ft/s.
88 feet — roughly the length of 6 average cars parked bumper-to-bumper.
Total stopping distance = reaction distance (speed × reaction time) + braking distance (varies with friction and speed²).
Yes. 1 mph = 5280/3600 ft/s = 22/15 ft/s exactly.
Kinetic energy increases with the square of speed. Doubling speed from 30 to 60 mph quadruples the kinetic energy and greatly increases crash severity.
25 mph = 36.67 ft/s — typical school zone speed.
Radar guns measure speed in mph or km/h using the Doppler effect, then display the converted value. Internal calculations may use ft/s.
