MPH to Feet per Second Converter

Convert miles per hour (mph) to feet per second (ft/s) — perfect for physics, vehicle testing, and safety calculations where you need speed per second instead of per hour.

Feet per second: –

Factor: 1 mph = 1.46667 ft/s

Reverse (ft/s → mph)

MPH to ft/s formula

The conversion is based on two exact definitions:

1 mile = 5280 feet
1 hour = 3600 seconds

1 mph = 5280 ÷ 3600 = 1.466666... ft/s

So the working formula is:

ft/s = mph × 1.46667

Example: 60 mph × 1.46667 ≈ 88.0 ft/s.

10 mph14.67 ft/s
20 mph29.33 ft/s
30 mph44.00 ft/s
40 mph58.67 ft/s
50 mph73.33 ft/s
60 mph88.00 ft/s

FAQ

Why convert to feet per second?

Feet per second is more convenient for physics problems, fall distance, or sports timing where events happen over a couple of seconds, not an hour.

Is 1.46667 exact?

1.466666... is repeating. We display 1.46667 which is good to 5 decimal places — more than enough for most engineering and school uses.
