Quick Answer
1 Newton = force to accelerate 1 kg by 1 m/s². 1 kgf = 9.807 N. 1 lbf = 4.448 N. The Newton is the SI standard; kgf and lbf are gravitational units that depend on standard gravity (9.80665 m/s²).

Design Notes
In electronics, relevant forces include connector insertion force (1-5N per pin), button actuation force (0.5-3N), and solder joint shear strength (20-60N). Force specifications appear in connector datasheets and mechanical reliability testing.
Common Mistakes
- 1
Confusing mass (kg) with force (N) — they are not interchangeable. 1 kg has a WEIGHT of 9.81 N on Earth.
- 2
Using lbf when lb (mass) was intended, or vice versa — the NASA Mars Climate Orbiter crash was caused by this.
- 3
Forgetting that kgf is NOT the same as kg — kgf is a force unit while kg is a mass unit.
Knowledge Base
Quelle est la différence entre newton et kilogramme-force ?
1 kgf = 9,80665 N (la force exercée par 1 kg sous la gravité terrestre). Le newton est l'unité SI. On utilise le kgf dans les spécifications de couple de serrage (Nm = kgf × bras).
