## Formula

- `1 kgf·m = 7.23301 lbf·ft`
- `pound-feet (ft-lb) = kilogram-force meters × 7.233013851`
- Reverse: `kilogram-force meters = pound-feet (ft-lb) × 0.1382549544`

The factor follows from the SI definitions of both units (NIST SP 811); values below are rounded to 6 significant figures, the API returns up to 12.

## Worked examples

- 5 kgf·m = 36.1651 lbf·ft
- 12.5 kgf·m = 90.4127 lbf·ft
- 100 kgf·m = 723.301 lbf·ft

## FAQ

**How many pound-feet (ft-lb) are in one kilogram-force meter?**

1 kgf·m = 7.23301 lbf·ft. The factor comes from the SI definitions of both units (NIST SP 811 / BIPM), so it is exact or correct to at least 10 significant figures.

**What is the formula to convert kilogram-force meters to pound-feet (ft-lb)?**

Multiply the value in kilogram-force meters by 7.233013851: pound-feet (ft-lb) = kilogram-force meters × 7.233013851. For example, 5 kgf·m = 36.1651 lbf·ft.

**How do I convert pound-feet (ft-lb) back to kilogram-force meters?**

Multiply by the inverse factor 0.1382549544 (kilogram-force meters = pound-feet (ft-lb) × 0.1382549544), or use the pound-feet (ft-lb)-to-kilogram-force meters page.
