How Much Is 138 Teaspoons of Cake Flour in Ounces?
138 teaspoons of cake flour weighs 11.56 oz. This is based on cake flour having a density of 114g per cup. Because teaspoons measure volume and ounces measure weight, the result depends on the ingredient, and a different ingredient would give a different result for the same 138 teaspoons.
Formula and Step-by-Step
- Start with 138 teaspoons of cake flour
- 1 teaspoon of cake flour = 2.38g
- 138 × 2.38 = 327.75g

Understanding the Units
What is a Teaspoon?
A US teaspoon is 4.929 ml, a metric teaspoon is exactly 5 ml, and an imperial teaspoon is 5.919 ml. The metric and US versions are nearly identical (1.4% difference), but the imperial teaspoon is 20% larger. For most spices the difference is negligible, but for leaveners like baking powder it can affect the result.
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.
