Miles Per Hour to Feet Per Second
Miles per hour is the standard speed unit on road signs and speedometers in the US and UK. Feet per second is used in the US to describe projectile velocity, such as bullet or arrow speed. 1 mph equals ≈1.46667 ft/s, so converting between them is a matter of multiplying by that fixed factor — type any value into the converter below and both sides update instantly as you type.
Both units belong to speed, measured here against speed's base unit (m/s) — every other speed unit on this site converts through that same reference point, which is why the table below can also be read as a quick cross-check against nearby values.
Formula
ft/s = mph × ≈1.46667
mph = ft/s × ≈0.681818
Worked example: 5 mph × ≈1.46667 = ≈7.33333 ft/s.
