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?

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 359.99 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 138.06 teaspoons: 138.06 × 2.61 = 359.99 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: 359.99 g ÷ 2.61 = 138.06 teaspoons. Or use the Grams to Teaspoons converter.
