How the Ounces to Grams Converter Works
Ounces and grams both measure weight (mass) — ounces in the US customary system, grams in the metric. One ounce equals about 28.3495 grams, so to convert ounces to grams you multiply by 28.3495, and to convert grams to ounces you divide. The converter also shows pounds and kilograms.
These are weight ounces (avoirdupois), not fluid ounces, so this tool is for solids — ingredients, parcels, portions. For liquid volume, use the fluid-ounces converter instead.
grams = ounces × 28.3495
