Frequently asked questions
What does this weight calculator do?
Convert a weight between kilograms, grams, pounds, ounces, and related units.
How do I use this weight calculator?
Enter a value and choose the source and target units.
What does the result mean?
The result is the same mass expressed in a new unit.
What should I check before relying on it?
Do not confuse weight units with volume measures.
Why isn't 1 kg exactly 2.2 lb?
2.2 is a rounded shortcut for quick estimates. The precise factor is 1 kg ≈ 2.20462262 lb, and this calculator uses the full-precision factor rather than the rounded one.
What's the difference between weight and mass?
In everyday use they're treated interchangeably, and that's how this calculator works — converting the mass units kilograms and grams alongside the everyday weight units pounds and ounces.
Can I use this for cooking or shipping conversions?
Yes, for weight-based amounts like a recipe's meat or flour weight, or a package's shipping weight — just note that cooking volume units like cups or milliliters are a separate, ingredient-dependent conversion, not a straight weight conversion.
