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 Teaspoon?
One teaspoon holds about 5 milliliters. There are 3 teaspoons in a tablespoon and 48 teaspoons in a cup. Teaspoon accuracy matters most with leaveners like baking powder and baking soda, where small differences affect rise and texture.
What is an Ounce?
An ounce (oz) is a US customary unit of weight equal to 28.3495 grams or 1/16 of a pound. In cooking, "ounces" refers to weight (avoirdupois ounces), not fluid ounces which measure volume.
Frequently Asked Questions
1 teaspoon of baking powder is 0.17 oz. The conversion depends on the density of baking powder and scales proportionally for any amount.
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 teaspoons 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 teaspoon 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.
