## Conversion factors (relative to Newton)

| Unit | Newton equivalent |
|------|------------------|
| Newton (N) | 1 |
| Kilonewton (kN) | 1 000 |
| Millinewton (mN) | 0.001 |
| Pound-force (lbf) | 4.44822 |
| Kilogram-force (kgf) | 9.80665 |
| Ounce-force (ozf) | 0.278014 |
| Dyne (dyn) | 0.00001 |
| Kilopound-force (kip) | 4 448.22 |

## Worked example

A typical car engine produces about **200 lbf** of thrust at idle.

Converting to Newtons: 200 × 4.44822 = **889.6 N**

Converting to kgf: 889.6 ÷ 9.80665 ≈ **90.7 kgf**

## Notes

- Newton (N) is the SI unit of force: 1 N = 1 kg·m/s².
- Kilogram-force (kgf) is sometimes called "kilopond" (kp) in older European texts.
- Conversion factors follow NIST Guide to the SI (2008), Appendix B.

## Frequently asked questions

### How does the force converter work?

Every unit is first converted to the base unit (Newton) by multiplying by a fixed factor, then divided by the target unit's factor to get the result.

### What is the difference between Newton and kilogram-force?

A Newton (N) is the SI unit of force. One kilogram-force (kgf) equals the force exerted by gravity on a 1 kg mass, which is 9.80665 N.

### What is a pound-force?

A pound-force (lbf) is the force exerted by gravity on a 1 pound mass under standard gravity. One lbf equals approximately 4.44822 N.

### What is a dyne?

A dyne is the CGS unit of force. One dyne equals 10⁻⁵ Newtons, or 0.00001 N.

### What units are supported?

Newton (N), kilonewton (kN), millinewton (mN), pound-force (lbf), kilogram-force (kgf), ounce-force (ozf), dyne (dyn), and kilopound-force (kip).
