About this tool
Convert pounds per second to kilograms per second instantly. Free, bidirectional, and fully in-browser.
1 pound per second equals 0.45359237 kilograms per second — enter any pound per second value to convert it to kilograms per second instantly. This Pound per second to Kilogram per second converter is a client-side tool: it applies a single multiplication (kg/s = lb/s × 0.45359237) in your browser, updates the moment you type, and works in both directions — edit either field, or press swap, to convert kilograms per second back to pounds per second. A reference table lists common pound per second values already converted, and nothing you enter is sent to a server.
Open Pound per second to Kilogram per second Converter on AltFTool — it loads instantly in your browser.
Type the value you want to convert into the Pound per second field.
Read the equivalent in kilograms 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 kilograms per second to pounds per second.
The result updates as you type, and the swap button flips the conversion to kilogram per second → pound per second without reloading.
The conversion uses the precise factor (kg/s = lb/s × 0.45359237), 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.
