Force Converter
Convert force between newtons, kilonewtons, pounds-force, kilograms-force, dynes and poundals.
Change the values and press Calculate to work out your own figures.
Enter a force, choose its unit and the unit you want. The answer is exact until it is shown, and the same value appears in every other unit.

- 1 lbf = 4.44822161526 N
- 1 × 4.44822161526 = 4.44822161526 N
How to use it
Type a force, choose the unit it is in and the unit you want, then press Calculate. You can type decimals, fractions such as 3/8, mixed numbers such as 1 1/2, very large or small numbers such as 2.5e6, and simple sums such as 2*3. Swap exchanges the two units.
The answer is worked out with exact fractions and only rounded for display, to 12 significant figures. Below it you get the same value in every other unit on the list, and Show the working gives the factor that was used.
Key definitions
1 N = 1 kg·m/s² 1 kgf = 9.80665 N 1 lbf = 4.4482216152605 N
Mass and force
A kilogram is a mass; a kilogram-force is the weight of that mass under standard gravity, 9.80665 newtons. The same goes for the pound and the pound-force. Engineering specifications in newtons or pounds-force describe forces, not masses.
Questions
