Formula and Step-by-Step

teaspoons × 2.38g/tsp = grams
  1. Start with 4.21 teaspoons of cake flour
  2. 1 teaspoon of cake flour = 2.38g
  3. 4.21 × 2.38 = 10.00g

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

Measuring Tip

For the most consistent results, weigh cake flour on a kitchen scale. Volume measurements can vary by 20-30% depending on how the flour is scooped.

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 a Gram?

A gram (g) is a metric unit of mass equal to 1/1000 of a kilogram. It is the standard weight measurement for precise baking worldwide. Professional bakers prefer grams because they are more accurate than volume measurements.

Frequently Asked Questions

About 10.00 g, 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). For 4.21 teaspoons: 4.21 × 2.38 = 10.00 g.
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.
Reverse the conversion: 10.00 g ÷ 2.38 = 4.21 teaspoons. Or use the Grams to Teaspoons converter.
