How it's calculated
The value is changed to kilograms, then to the unit you choose. The pound has been defined as exactly 0.45359237 kg since 1959; an ounce is 1/16 lb, a stone 14 lb, a US short ton 2,000 lb and a UK long ton 2,240 lb.
Gold and silver are priced per troy ounce (31.1034768 g), which is heavier than an ordinary ounce (28.349523125 g). In Gulf and South Asian gold markets the tola is common: 180 grains, or 11.6638038 g. A carat (200 mg) measures gemstones; gold purity “karat” is a different thing.
Strictly, kilograms measure mass, not weight. Day to day the two words are used the same way; for weight as a force (newtons) use the weight force calculator.
