This free weight converter lets you switch instantly between pounds, kilograms, ounces, grams, stone, and tonnes. It's bidirectional — every input pair works both ways, so you never have to remember which direction to convert.
Cooking & baking: Many Australian recipes list ingredients in grams, while American and UK recipes often use ounces or cups. Converting 200 g of flour to ounces (roughly 7 oz) or checking that 500 g of mince is just over a pound helps you follow any recipe accurately.
Shipping & courier services: Parcel costs are weight-dependent, and international couriers often quote limits in kilograms while some domestic services still list pounds. Knowing whether your 10 kg parcel is under a 25 lb threshold can save on shipping charges.
Health & fitness: Body weight is tracked in kilograms in Australia and most of the world, but in pounds in the US and stones/pounds in the UK. If you're following a US-based fitness programme that references your weight in pounds, this converter keeps you on track without mental arithmetic.
International travel: Airline baggage allowances are listed in kilograms internationally but in pounds on some US carriers. A 23 kg limit is approximately 50.7 lb — checking this before you pack prevents expensive overweight fees at check-in.
One stone equals exactly 14 pounds, which is 6.35029 kg. Stone is commonly used for body weight in the UK and Ireland. So if someone says they weigh 11 stone, that's 154 lb or roughly 69.9 kg.
No. A metric tonne (1,000 kg) is slightly heavier than a US short ton (2,000 lb ≈ 907.2 kg). There is also a UK long ton (2,240 lb ≈ 1,016 kg). This converter uses the metric tonne vs US short ton pairing, which is the most common source of confusion.
