How Much Is 12 Teaspoons of Self-Rising Flour in Grams?

12 teaspoons of self-rising flour weighs 30.00 g. This is based on self-rising flour having a density of 120g per cup. Because teaspoons measure volume and grams measure weight, the result depends on the ingredient, and a different ingredient would give a different result for the same 12 teaspoons.

Formula and Step-by-Step

teaspoons × 2.5g/tsp = grams
  1. Start with 12 teaspoons of self-rising flour
  2. 1 teaspoon of self-rising flour = 2.5g
  3. 12 × 2.5 = 30g

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

Measuring Tip

Different flour types have very different weights per cup. Always check the specific flour your recipe calls for rather than using a generic "flour" conversion.

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 a Gram?

Grams are the preferred unit in professional kitchens and bakeries because they allow exact recipe scaling. To double a recipe, simply double the gram values. No need to worry about how tightly an ingredient is packed into a cup.

Frequently Asked Questions

About 30.00 g, based on self-rising flour having a density of 120g per cup. The exact amount depends on how the ingredient is measured and the specific product.
Multiply the number of teaspoons by 2.5 (grams per teaspoon for self-rising flour). For 12 teaspoons: 12 × 2.5 = 30.00 g.
For the most accurate results, weigh self-rising 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 120 grams per cup. If you dip directly into the flour bag and sweep level, the flour packs tighter and you can end up with 132 to 150 grams per cup instead. This conversion uses the spoon-and-level method, which is the standard most baking references follow.
Reverse the conversion: 30.00 g ÷ 2.5 = 12 teaspoons. Or use the Grams to Teaspoons converter.
