How it works
- Converted value = × f₁ / f₂
- 1 kgf = 9.80665 N; 1 lbf = 4.4482216152605 N; 1 dyn = 10⁻⁵ N

Assumptions and limitations
Force is distinct from mass. kgf and lbf use standard gravity, not local gravity. Negative values can represent signed force components. No load-rating calculation. Example: 1 kgf = 9.80665 N; 1 lbf = 4.4482216152605 N.
