⚖️ Weight Converter
kg, lbs, oz, stone, grams and metric tons
About this calculator
Kilograms, pounds, grams, ounces, tonnes — enter a weight in any unit and get all the equivalents instantly. Uses exact factors (1 lb = 0.45359237 kg) and also covers stone and troy ounces for UK and precious-metal contexts, from milligrams to metric tonnes. Useful for recipes, luggage limits, shipping quotes, and loading gym plates.
Tip: airline baggage limits are usually 23 kg (50 lb) in economy — convert before you pack, not at the check-in counter — and remember the limit includes the bag itself.
