The Carat of The Romans and Greeks
The solidus was also a Roman weight unit. There is literary evidence that the weight of 72 coins of the type called solidus was exactly 1 Roman pound, and that the weight of 1 solidus was 24 siliquae. The weight of a Roman pound is generally believed to have been 327.45 g or possibly up to 5 g less. Therefore, the metric equivalent of 1 siliqua was approximately 189 mg. The Greeks had a similar unit of the same value.
Gold fineness in carats comes from carats and grains of gold in a solidus of coin. One solidus = 24 carats, 1 carat = 4 grains, is preserved right up to this day. Woolhouse's Measures, Weights and Moneys of all Nations gives gold fineness in carats of 4 grains, and silver in (pound) of 12 ounces each 20 dwt.
