About This Conversion

Ounces to grams turns US recipes and product weights into something a metric kitchen scale can follow. Sixteen ounces make a pound, so a 16 oz result of 453.6 g is a useful checkpoint that the arithmetic is right.

Precious metals do not use this ounce. Gold and silver are priced in troy ounces of 31.1035 g, about 10 percent heavier than the avoirdupois ounce used for food and freight, so quoting a bullion weight with the standard factor understates it substantially.
