About the Weight Converter
Weight conversions are needed daily — for cooking recipes, body weight, postage, gym tracking and international shopping. The metric system uses grams and kilograms while the imperial system uses ounces, pounds and stone. This converter handles all common weight units with a live reference table.
Common uses: converting body weight between kg and lbs, cooking conversions between grams and ounces, understanding parcel weight limits, and comparing nutritional information across countries.
Key relationships: 1 kilogram = 2.205 pounds, 1 pound = 453.6 grams, 1 stone = 14 pounds = 6.35 kg, 1 ounce = 28.35 grams. Body weight in the UK is often discussed in stone and pounds (e.g., 11 st 4 lbs), while medicine and most other countries use kilograms. Nutritional labels in the US list values per ounce while European labels use grams.
Postal and shipping weight limits are almost always in kilograms internationally, but some US carriers quote in pounds. For cooking, American recipes list ingredients in ounces and cups while European recipes use grams. The reference table shows all weight equivalents at once for the value you enter.
