Convert pounds-force to kilograms-force instantly. Free, bidirectional, and fully in-browser.
1 pound-force equals 0.45359237 kilograms-force — enter any pound-force value to convert it to kilograms-force instantly. This Pound-force to Kilogram-force converter is a client-side tool: it applies a single multiplication (kgf = lbf × 0.45359237) in your browser, updates the moment you type, and works in both directions — edit either field, or press swap, to convert kilograms-force back to pounds-force. A reference table lists common pound-force values already converted, and nothing you enter is sent to a server.
Open Pound-force to Kilogram-force Converter on AltFTool — it loads instantly in your browser.
Type the value you want to convert into the Pound-force field.
Read the equivalent in kilograms-force in the result field, and copy it if needed.

The result updates as you type, and the swap button flips the conversion to kilogram-force → pound-force without reloading.
The conversion uses the precise factor (kgf = lbf × 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.
