One ounce is a common unit of measure used for a range of things. When it comes to dry goods, such as ingredients used in cooking and baking, 1 oz is equivalent to approximately 2 tablespoons or 28.35 grams. Depending on the ingredient you're measuring, an ounce can be equal to roughly one cup or 3 teaspoons as well. If you are using measurement tools like scales which measure weight rather than volume when measuring ounces of dry goods it's important to understand that the weight will vary depending on the item being measured due to differences in density between items such as flour and sugar.
