How to Use Force Converter
The Force Converter turns a force value into every common unit immediately. Type a number, choose the source unit, and switch to the target unit. The Force Converter is intended for physics, engineering, mechanical design and any spec sheet that mixes SI and US units.
- Enter the force value - Decimal and scientific notation are supported.
- Pick the source unit - N, kN, mN, dyn, lbf, ozf, kgf, gf or tf.
- Pick the target unit - The Force Converter shows the conversion and a full table of all units.
- Swap units - Use the Swap button to quickly reverse the direction.
Formula & Theory - Force Converter
The Force Converter uses newtons as the canonical SI unit:
N = value × factor(from)
result = N / factor(to)| Unit | Newtons per unit |
|---|---|
| Newton (N) | 1 |
| Kilonewton (kN) | 1000 |
| Millinewton (mN) | 0.001 |
| Dyne (dyn) | 10⁻⁵ |
| Pound-force (lbf) | 4.4482216152605 |
| Ounce-force (ozf) | 0.27801385095378 |
| Kilogram-force (kgf) | 9.80665 |
| Gram-force (gf) | 0.00980665 |
| Tonne-force (tf) | 9806.65 |
Reference values
- 1 N ≈ 0.224809 lbf ≈ 0.101972 kgf.
- 1 lbf = 16 ozf ≈ 4.4482 N.
- 1 kgf = 9.80665 N (standard gravity).
Assumptions and Limits
The Force Converter uses standard gravity g = 9.80665 m/s² for kgf, gf and tf. Local gravity differences are negligible for everyday calculations but matter for precision work.
Use Cases for Force Converter
The Force Converter is useful for many tasks:
- Mechanical engineering - Convert spec sheets between N and lbf.
- Physics homework - Move between CGS dynes and SI newtons.
- Material testing - Translate tensile or load values between kgf and N.
- Sports equipment - Compare resistance band or cable forces in different units.
- Aerospace - Work with kN and lbf for thrust values.
The Force Converter shows every unit at once, so cross-checking conversion factors is quick.
