Formula and Step-by-Step

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

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

Mental Math Shortcut

For 1 teaspoon of all-purpose flour, just remember: 2.61g. Double it for 2 teaspoons (5.22g), halve it for a half teaspoon (1.30g).

Measuring Tip

Humidity affects all-purpose 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?

A teaspoon (tsp) is a US customary unit of volume equal to 4.929 milliliters or 1/3 of a tablespoon. It is the standard measure for spices, leaveners, extracts, and other small-quantity ingredients.

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 2.61 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 1 teaspoon: 1 × 2.61 = 2.61 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: 2.61 g ÷ 2.61 = 1 teaspoon. Or use the Grams to Teaspoons converter.
