One kilogram is about 2.20462 pounds. A stone is 14 pounds (about 6.35 kg), commonly used for body weight in the UK.

A US (short) ton is 2,000 lb. A UK (long) ton is 2,240 lb. A metric tonne is 1,000 kg. Tweak the inputs above to compare options, then copy or note the result you need.

A UK stone is 14 lb. A US short ton is 2,000 lb; a UK long ton is 2,240 lb; a tonne is 1,000 kg. Shipping and body-weight conversations use these as if they were the same — they are not.

Kitchen scales in grams and parcel weights in kilograms should stay metric if the courier is metric. Convert at the end rather than after every ingredient. This is mass as used in everyday trade, not a lab balance certificate.
