Example: 1 ounce = 141.747616 carat

The everyday avoirdupois ounce is about 28.35 g, but precious metals are priced in troy ounces of about 31.10 g. An 'ounce of gold' is nearly 10% heavier than an ounce of flour. Use troy ounces for gold and silver, the regular ounce for everything else.
The carat used for gemstones is a unit of mass: exactly 0.2 g, so a 5-carat diamond weighs 1 gram. The karat used for gold is something else entirely, a purity scale where 24k is pure gold and 18k is 75% gold. The two cannot be converted into each other.
