Formula and Step-by-Step

teaspoons × 2.38g/tsp ÷ 28.3495g/oz = ounces
  1. Start with 1.5 teaspoons of cake flour
  2. 1 teaspoon of cake flour = 2.38g
  3. 1.5 × 2.38 = 3.56g
  4. Convert grams to ounces: 3.56 ÷ 28.3495 = 0.13 oz

The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.

Measuring Tip

Humidity affects cake flour weight. In humid conditions, flour absorbs moisture and weighs more per cup. Store it in an airtight container for consistent results.

Understanding the Units

What is a Teaspoon?

In baking, teaspoon measurements are critical for ingredients where precision changes the outcome. Too much baking soda (1 tsp = 6g) creates a metallic taste, while too little means flat results.

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 0.13 oz, based on cake flour having a density of 114g per cup. The exact amount depends on how the ingredient is measured and the specific product.
Multiply the number of teaspoons by 2.38 (grams per teaspoon for cake flour), then divide by 28.3495 to convert grams to ounces. For 1.5 teaspoons: 1.5 × 2.38 = 3.56g, then 3.56 ÷ 28.3495 = 0.13 oz.
For the most accurate results, weigh cake flour on a kitchen scale. If measuring by volume, sift or whisk first to break up clumps, then spoon into the measuring spoon and level off. Do not scoop directly from the bag.
Yes, quite a bit. If you spoon the flour into your measuring spoon and level it off, you will get about 114 grams per cup. If you dip directly into the flour bag and sweep level, the flour packs tighter and you can end up with 125.4 to 142.5 grams per cup instead. This conversion uses the spoon-and-level method, which is the standard most baking references follow.
