How weight conversion works
Weight conversions go through the kilogram. The international avoirdupois pound is defined as exactly 0.45359237 kg, so 1 kg is about 2.2046 lb, and an ounce is one sixteenth of a pound, about 28.35 grams.
A stone, still used for body weight in the UK and Ireland, is 14 pounds or about 6.35 kg. Troy ounces, used for gold and silver, are heavier than ordinary ounces at about 31.1 grams.
