To convert ounces to grams, multiply by 28.3495. So 8 oz × 28.3495 = 226.8 g, and 16 oz (1 lb) = 453.6 g. A useful shortcut: multiply ounces by 28 and add 1% for a close approximation.
American recipes almost always use ounces for dry ingredients, while European and metric recipes use grams. Converting between them is essential for any cook working across both traditions. The baking industry often requires precise gram measurements for consistent results at scale.
Did you know? The troy ounce — used for gold, silver, and other precious metals — is heavier than the regular (avoirdupois) ounce: 31.1035 g vs. 28.3495 g. Always confirm which ounce a weight refers to when dealing with precious metals.
Gold and silver prices are quoted per troy ounce globally, but jewelers and investors often verify in grams. American product packaging lists net weight in ounces, which must be converted to grams for EU import/export documentation. Food portion control apps frequently require gram values.
