Oz to Grams for Cooking and Baking
Recipes from different countries may use ounces or grams. Converting the weight rather than guessing is especially useful for baking because small changes in ingredient quantities can affect the final result. When a recipe specifies weight ounces, this calculator can provide the gram equivalent.
Remember that weight ounces are different from fluid ounces. A fluid ounce measures volume, so converting fluid ounces to grams requires information about the liquid or ingredient being measured.
