Why this tool is useful
Use this converter when specifications, downloads or measurements are given in miles per hour, but your worksheet or destination requires feet per second. It avoids manual factor mistakes.

Convert miles per hour (mph) to feet per second (ft/s) with a transparent speed formula.
Ready. Your working data stays in this browser.
Use this converter when specifications, downloads or measurements are given in miles per hour, but your worksheet or destination requires feet per second. It avoids manual factor mistakes.
The browser converts mph to the shared speed base unit using scale 0.44704 and offset 0, then converts that base value to ft/s using scale 0.3048 and offset 0.
For example, entering 1 mph returns 1.466666667 ft/s. Results include the formula and enough precision for a quick verification.
The calculation is deterministic and explains validation errors instead of silently changing invalid input.
Input and output remain in this tab. Copy and download happen through browser APIs without a server upload.
Every run reports its tool mode, timestamp and input/output size so transformed data can be audited.
