Understanding the Units

What is a Tablespoon?

A tablespoon (tbsp) is a US customary unit of volume equal to 14.787 milliliters, 3 teaspoons, or 1/16 of a cup. It is commonly used for measuring smaller amounts of ingredients.

What is an Ounce?

Weight ounces and fluid ounces are different measurements. A fluid ounce measures volume (29.574 ml), while an ounce measures weight (28.35g). They only align for water, where 1 fl oz weighs approximately 1 oz.

Frequently Asked Questions

About 21.56 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.
