Weight Converter
Convert mass among mg, g, kg, metric tonnes, oz, lb, and stone using kilograms as the reference.
How to use
- Enter a mass value and choose its original and required units such as kg, g, lb, oz, or stone.
Capabilities and scope
Although commonly called a weight converter, the values here are mass units rather than force measured in newtons.
How it works
Kilograms are the reference. The implementation uses 1 lb = 0.45359237 kg, 1 oz = 0.0283495231 kg, and 1 stone = 6.35029318 kg.
Example
1 kg is approximately 2.20462 lb.
Useful for
- Compare body mass in kg and lb
- Convert shipping mass from oz/lb to kg
- Convert metric tonnes and kilograms
Before you use it
- It does not convert gravitational force in newtons. Mass and physical weight force are different quantities.

Frequently asked questions
Can I convert kg to N here?
No. kg is mass and N is force, so a force calculation and a gravity assumption are required.
