How does the weight converter work?
This weight converter uses precise conversion factors to instantly translate measurements between four common units: kilograms (kg), pounds (lbs), ounces (oz), and grams (g). Enter any value, choose your starting unit and target unit, and the result appears immediately. All conversions use internationally recognized standards — 1 kg = 2.20462 lbs, 1 lb = 16 oz, 1 kg = 1000 g. The converter works for cooking, fitness, shipping, and any situation where you need to switch between metric and imperial weight units.
How to use the Weight Converter
Enter the amount you want to convert, select the source unit (e.g. kilograms) and the target unit (e.g. pounds). Click "Convert" to see the exact equivalent. You can switch between any of the four units — the conversion works in both directions with the same accuracy. Decimal values are fully supported.
