What is the SI unit of force?

The SI unit of force is the Newton (N). 1 Newton = 1 kg·m/s² — the force needed to accelerate 1 kg by 1 m/s².

How do I convert Newton to kilogram-force?

1 kgf = 9.80665 N. To convert N to kgf, divide by 9.80665. Example: 100N = 10.197 kgf. This is the weight of approximately 1 kg mass.

1 pound-force (lbf) = 4.44822 N. It's the force exerted by gravity on 1 pound mass. Used in US engineering for structural calculations.

What is the difference between mass and force?

Mass measures amount of matter (kg). Force = mass × acceleration (N). Weight is a force — Earth's gravity exerts 9.8 N on each kilogram of mass.

How much force does a human exert when walking?

Normal walking generates ground reaction forces of 1.0-1.5 times body weight. Running generates 2-3 times body weight. This matters for joint health and prosthetic design.

Frequently Asked Questions

Q: What is a Newton?

1 Newton (N) is the force needed to accelerate 1 kg by 1 m/s². Earth's gravity exerts about 9.81 N on every 1 kg (your weight in Newtons ≈ kg × 9.81).

Q: What is kilogram-force (kgf)?

1 kgf is the force exerted by 1 kg under standard gravity = 9.80665 N. Used in engineering in India and many countries. A 70 kg person has weight of 70 kgf = 686.5 N.
