Understanding the Units

What is a Tablespoon?

A tablespoon (tbsp) is a US customary unit of volume equal to 14.787 milliliters, 3 teaspoons, or 1/16 of a cup. It is commonly used for measuring smaller amounts of 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

How many grams is 12.5 tablespoons of cornstarch? expand_more

About 100.00 g, based on cornstarch having a density of 128g per cup. The exact amount depends on how the ingredient is measured and the specific product.

What is the formula for converting tablespoons of cornstarch to grams? expand_more

Multiply the number of tablespoons by 8 (grams per tablespoon for cornstarch). For 12.5 tablespoons: 12.5 × 8 = 100.00 g.

How do I measure cornstarch accurately? expand_more

For the most accurate results, weigh cornstarch 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.

Does the measurement method affect how much cornstarch weighs per cup? expand_more

Yes, quite a bit. If you spoon the flour into your measuring spoon and level it off, you will get about 128 grams per cup. If you dip directly into the flour bag and sweep level, the flour packs tighter and you can end up with 140.8 to 160 grams per cup instead. This conversion uses the spoon-and-level method, which is the standard most baking references follow.

How do I convert grams of cornstarch back to tablespoons? expand_more

Reverse the conversion: 100.00 g ÷ 8 = 12.5 tablespoons. Or use the Grams to Tablespoons converter.
