Understanding the Units

What is a Tablespoon?

One tablespoon holds about 15 milliliters. There are 16 tablespoons in a cup and 3 teaspoons in a tablespoon. In baking, tablespoon measurements are used for butter, oil, honey, and other ingredients where a full cup would be too much.

What is an Ounce?

Ounces are commonly used in US recipes for cheese, meat, chocolate, and other ingredients sold by weight. Many kitchen scales offer both gram and ounce readings.

Frequently Asked Questions

About 64.90 oz, based on baking powder having a density of 230g per cup. The exact amount depends on how the ingredient is measured and the specific product.
