Force units
Force changes the motion of a mass. The SI unit is the newton: the force that accelerates one kilogram by one meter per second squared.
| Unit | Symbol | In newtons | Definition |
|---|---|---|---|
| Newton | N | 1 N | The SI unit of force: 1 kg·m/s². |
| Kilonewton | kN | 1,000 N | |
| Dyne | dyn | 0.00001 N | |
| Pound-force | lbf | 4.448221615 N | The force of gravity on one pound at standard gravity: about 4.448 newtons. |
| Kilogram-force | kgf | 9.80665 N | The force of gravity on one kilogram at standard gravity: exactly 9.80665 newtons. |
| Ounce-force | ozf | 0.278013851 N | |
| Kip | kip | 4,448.221615 N | One thousand pound-force. |
Calculate with force
The smart calculator does arithmetic across force units and picks a sensible unit for the answer. Try 10 kg × 9.80665 m/s² to N.
Questions and answers
Which force units can I convert?
All 7: newtons, kilonewtons, dynes, pound-forces, kilogram-forces, ounce-forces, kips.
What is the SI unit of force?
This converter uses the newton (N) as its base unit. Force changes the motion of a mass. The SI unit is the newton: the force that accelerates one kilogram by one meter per second squared.
How precise are the results?
Factors are the exact legal definitions where one exists (an inch is exactly 2.54 cm, a pound exactly 0.45359237 kg). Results show 10 significant digits by default; the precision menu offers 4 to 15.
Does the force converter work offline?
Yes. ConvertEasy is a progressive web app: after your first visit it keeps working with no connection, and you can install it to your home screen from the browser menu.
