Grains in jewellery, medicine and ammunition
The grain is the smallest unit of the imperial and troy systems and is identical in both: 1 grain = 64.79891 milligrams, so about 15.43 grains make 1 gram.
It is still used for bullets and gunpowder, some medicine doses (for example 5 grains of aspirin ≈ 324 mg) and, historically, for gold and pearls. Do not confuse it with the carat (0.2 g) used for gemstones.
