Formula and Step-by-Step

teaspoons × 2.61g/tsp = grams
  1. Start with 4.2 teaspoons of all-purpose flour
  2. 1 teaspoon of all-purpose flour = 2.61g
  3. 4.2 × 2.61 = 10.95g

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?

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 a Gram?

Weighing ingredients in grams eliminates the variability of volume measurements. A cup of flour can weigh anywhere from 120g to 160g depending on how it was scooped, but 120g of flour is always 120g of flour.

Frequently Asked Questions

About 10.95 g, based on all-purpose flour having a density of 125.16g per cup. The exact amount depends on how the ingredient is measured and the specific product.
Multiply the number of teaspoons by 2.61 (grams per teaspoon for all-purpose flour). For 4.2 teaspoons: 4.2 × 2.61 = 10.95 g.
For the most accurate results, weigh all-purpose 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 125.16 grams per cup. If you dip directly into the flour bag and sweep level, the flour packs tighter and you can end up with 137.68 to 156.45 grams per cup instead. This conversion uses the spoon-and-level method, which is the standard most baking references follow.
Reverse the conversion: 10.95 g ÷ 2.61 = 4.2 teaspoons. Or use the Grams to Teaspoons converter.
