Frequently asked questions

How do I convert kilogram-force to newton?

1 kilogram-force = 9.80665 newton. Choose "Kilogram-force (kgf)" as From and "Newton (N)" as To, type a value, and the result updates instantly.

Is kilogram a unit of force?

Strictly no — the kilogram measures mass. The kilogram-force (kgf) is the weight of 1 kg under standard gravity: exactly 9.80665 N. Scales labeled "kg" report mass assuming that gravity.

What is a poundal?

The poundal is the force that accelerates 1 lb at 1 ft/s² — exactly 0.138254954376 N. It appears in older engineering texts using the absolute foot-pound-second system.

Is my data sent to a server?

No. Conversions run entirely in your browser using fixed factors — nothing is uploaded or logged.
