About this tool
Convert miles per hour to feet per second instantly. Free, bidirectional, and fully in-browser.
1 mile per hour equals 1.466666667 feet per second — enter any mile per hour value to convert it to feet per second instantly. This Mile per hour to Foot per second converter is a client-side tool: it applies a single multiplication (ft/s = mph × 1.466666667) in your browser, updates the moment you type, and works in both directions — edit either field, or press swap, to convert feet per second back to miles per hour. A reference table lists common mile per hour values already converted, and nothing you enter is sent to a server.
Open Mile per hour to Foot per second Converter on AltFTool — it loads instantly in your browser.
Type the value you want to convert into the Mile per hour field.
Read the equivalent in feet per second in the result field, and copy it if needed.
Use the decimal-places slider for more or less precision, or press swap to convert feet per second to miles per hour.
The result updates as you type, and the swap button flips the conversion to foot per second → mile per hour without reloading.
The conversion uses the precise factor (ft/s = mph × 1.466666667), so the number matches a manual calculation to the decimal places you choose.
A slider sets 0–10 decimal places, and very small or very large results switch to scientific notation instead of rounding to zero.
Everything runs locally in your browser — no upload, no account, no limit on conversions.

It uses the standard speed and velocity definition (ft/s = mph × 1.466666667), not a rounded approximation, so results are exact to the number of decimal places you select.
