Weight Converter
The Weight Converter converts mass and weight between metric and imperial units — milligrams, grams, kilograms, tonnes, ounces, pounds and stones. Useful for cooking, fitness, shipping and everyday comparisons.
What this means
Weight and mass tell you how heavy an object is. Metric units (grams, kilograms, tonnes) are based on the kilogram; imperial units (ounces, pounds, stones) have exact metric definitions. The converter multiplies by the exact ratio between them.
How we calculate it
Formula
Result = Value × (factor of source unit) ÷ (factor of target unit). Each unit is defined exactly against the kilogram (1 lb = 0.45359237 kg).Worked example
How many pounds is 1 kilogram?
- 11 kg = 1 kg, and 1 lb = 0.45359237 kg
- 2Factor = 1 ÷ 0.45359237 ≈ 2.20462262
- 31 kilogram ≈ 2.2046 pounds
Important assumptions
- Factors use exact international definitions (1 lb = 0.45359237 kg, 1 oz = 28.349523125 g).
