Force Converter
Convert force among N, kN, dyne, kgf, and lbf using the newton as the reference.
How to use
- Enter a force and select the source and destination among N, kN, dyne, kgf, and lbf.
Capabilities and scope
These are force units, not mass units, allowing SI newtons to be compared with gravitational units such as kgf and lbf.
How it works
The implementation uses 1 dyn=10⁻⁵ N, 1 kgf=9.80665 N, and 1 lbf≈4.4482216153 N.
Example
1 kgf is exactly 9.80665 N by the standard-gravity definition used here.
Useful for
- Convert kgf loads to N
- Compare lbf with SI force
- Convert CGS dyne values to newtons
Before you use it
- A kilogram of mass is not automatically treated as kgf, and local gravitational acceleration is not modeled.

Frequently asked questions
Is 1 kg of mass always 1 kgf of weight?
kgf is defined using standard gravity; the actual weight of a mass can vary with local gravity.
