How force conversion works
Every force unit has a fixed ratio to the newton (N), the SI unit of force. The value is first converted to newtons, then into the target unit.
Common values
| Value (kgf) | Result |
|---|---|
| 0.1 kgf | 0.980665 N |
| 0.25 kgf | 2.45166 N |
| 0.5 kgf | 4.90332 N |
| 1 kgf | 9.80665 N |
| 1.5 kgf | 14.71 N |
| 2 kgf | 19.6133 N |
| 3 kgf | 29.42 N |
| 5 kgf | 49.0332 N |
| 10 kgf | 98.0665 N |
More detail
Where each unit is used
N (newton) is the SI unit used in physics and engineering. kgf (kilogram-force) shows up on older scales, torque wrenches, and lifting equipment. lbf (pound-force) is standard in US engineering. dyn (dyne) is the CGS unit still seen in some physics references.
What a kilogram-force is. 1 kgf = 9.80665 N exactly — the force gravity exerts on a 1 kg mass. So a 70 kg person presses on the floor with about 687 N.
Frequently asked questions
How many newtons is 1 kgf?
1 kgf = 9.80665 N exactly, based on standard gravity (9.80665 m/s²). Enter your own value above for the exact conversion.
How many newtons is 1 lbf?
1 lbf ≈ 4.44822 N. For example, 10 lbf ≈ 44.4822 N.
How do I convert a scale reading in kgf to newtons?
Multiply by 9.80665. For example, a 70 kgf reading is 686.4655 N — enter 70 above with kgf → N and the calculator shows 686.465, rounded to six significant figures.
How many dynes is 1 newton?
1 N = 100,000 dyn (10⁵ dyn), since the dyne is the smaller CGS unit of force.
