Measuring Tip
Leavener measurements are critical because even small differences affect rise and texture. When possible, weigh baking powder rather than relying on volume.
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.

The most accurate way is to weigh baking powder on a kitchen scale, especially at small quantities where precision matters most. If measuring by volume, dip the spoon into the container and level it off with a straight edge. Do not tap or shake the spoon, which settles the powder and increases the amount.
Close, but not exactly. The tablespoons to ounces conversion for baking powder may vary slightly between brands depending on moisture content and how the ingredient is measured.
Weighing is more consistent than volume measuring. A tablespoon of baking powder can vary by 10-20% depending on how it's scooped, packed, or leveled. Weighing gives the same result every time, which is especially important in baking where precision affects texture and rise.
