About this tool
Convert feet per second squared to km/h/s instantly. Free, bidirectional, and fully in-browser.
1 foot per second squared equals 1.09728 km/h/s — enter any foot per second squared value to convert it to km/h/s instantly. This Foot per second squared to Kilometer per hour per second converter is a client-side tool: it applies a single multiplication (km/h/s = ft/s² × 1.09728) in your browser, updates the moment you type, and works in both directions — edit either field, or press swap, to convert km/h/s back to feet per second squared. A reference table lists common foot per second squared values already converted, and nothing you enter is sent to a server.

The result updates as you type, and the swap button flips the conversion to kilometer per hour per second → foot per second squared without reloading.
The conversion uses the precise factor (km/h/s = ft/s² × 1.09728), 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.

One foot per second squared is 1.09728 km/h/s. Multiply the foot per second squared value by 1.09728 to convert. For example, 10 ft/s² = 10.9728 km/h/s.
km/h/s = ft/s² × 1.09728. This tool applies it automatically and shows a worked example: 10 ft/s² = 10.9728 km/h/s.
Yes. Press the swap button, or type into the kilometer per hour per second field, and the tool converts km/h/s to feet per second squared using the inverse of the same relationship.
It uses the standard acceleration definition (km/h/s = ft/s² × 1.09728), not a rounded approximation, so results are exact to the number of decimal places you select.
Yes. The converter is a browser-side script with no network calls: your values are never uploaded, and once the page has loaded it keeps working without a connection.
