maratoolHow to convert newtons, kgf, and pounds-force
Type a force value — read newtons, kgf, lbf, dynes, or poundals instantly.
Datasheets mix newtons, kgf, and lbf constantly — especially for load cells, actuators, and fasteners. The Force Converter converts between them with exact NIST SP 811 factors.
How it works
- Pick units — "Kilogram-force (kgf)" to "Newton (N)", or any other pair.
- Type a value — the result updates as you type, with swap and copy.
- Copy — one click, with "Copied!" feedback.
Force conversion factors
Every unit converts through the newton (the base unit). To convert A → B, multiply by A's factor and divide by B's:
| Unit | = this many newtons |
|---|---|
| Newton (N) | 1 |
| Kilonewton (kN) | 1,000 |
| Kilogram-force (kgf) | 9.80665 |
| Gram-force (gf) | 0.00980665 |
| Pound-force (lbf) | 4.448221615261 |
| Ounce-force (ozf) | 0.278013850954 |
| Poundal (pdl) | 0.138254954376 |
| Dyne (dyn) | 1.0000 × 10^-5 |
When you need it
Quick anchors: 1 kgf = 9.80665 N exactly, 1 lbf = 4.448 N, and 100 N ≈ 22.5 lbf ≈ 10.2 kgf. When a spec says a button needs "3 N of actuation force", that is about 306 grams-force.
Sources & methodology
Conversion factors follow NIST Special Publication 811; exact-by-definition factors are marked in the tool itself. All math runs client-side in your browser — nothing is uploaded.
