How to convert ounces to grams
One ounce (avoirdupois, the everyday ounce for food and parcels) is 28.3495 grams, so multiply ounces by 28.3495 to get grams. For example, 8 oz × 28.3495 = 226.8 g. This is a weight ounce, not a US fluid ounce, which measures volume. The converter above shows grams, pounds and kilograms at the same time.
