About Force Units

Convert force between newtons, pounds-force, kilogram-force, dynes, and more.

One newton accelerates one kilogram at one meter per second squared — everything else converts from there, including the exact 4.44822 N pound-force. Kilogram-force (kiloponds) appears in older European specs; poundals and dynes survive mostly in textbooks.

Mass-versus-force confusion causes real errors: kilograms measure mass, newtons measure the force gravity exerts on it. Everything runs in your browser.

Where it is used

Physics homework, reading imperial datasheets, gym plate math in newtons, and engineering specs.

How to use the Force Units

  1. Value — enter the value (e.g. 100).
  2. From — enter the value.
  3. To — enter the value.

Frequently Asked Questions

Kilograms or newtons for weight?
Scales read mass (kg); weight as a force is newtons (mass × 9.81). Everyday speech mixes them — engineering must not.
What is a poundal?
The force accelerating one pound at one foot per second squared (≈0.138 N). Rare outside American physics textbooks.
Why 4.44822 exactly?
The international pound is defined as exactly 0.45359237 kg, times standard gravity 9.80665 m/s² — no measurement involved.
