- Exact definition
- 1 kgf = 9.806 65 N; 1 lbf = 4.448 221 615 N (both exact)
- Formula
- N = lbf × 4.448 22; N = kgf × 9.806 65
- Reverse
- lbf = N ÷ 4.448 22; kgf = N ÷ 9.806 65
- Worked example
- A 1,000 kg load weighs 9.807 kN = 2,204.6 lbf under standard gravity
- Rounding
- Matrix values use 6 significant figures. Weight = mass × 9.806 65 m/s² (standard gravity).
