Cornmeal: Cups to Grams
One US cup (240 ml) of cornmeal weighs 122 grams; half a cup weighs 61 grams. A quarter cup is 30.5 grams, a tablespoon is 7.63 grams and a teaspoon is 2.54 grams. A cup measures volume, not weight, so these numbers are for cornmeal only: a cup of honey weighs 340 grams.

Ounces here are ounces of weight (1 oz = 28.35 g), not fluid ounces. One US cup is 8 fluid ounces of volume whatever is in it, but what it weighs in ounces depends on the ingredient: a cup of cornmeal weighs about 4.3 oz. Why these two are not the same. Decimals for thirds are rounded (1/3 cup is 0.333 cups), and each linked amount opens a page comparing every ingredient at that measure.

About measuring cornmeal
Cornmeal is ground dried corn with a gritty texture, and one US cup weighs about 122 grams. It comes in fine, medium and coarse grinds, and the coarser it is the more it varies when measured by volume. In cornbread and polenta, the ratio of cornmeal to liquid decides whether you get a tender crumb or a heavy brick, so weighing brings welcome consistency, especially across different brands and grinds.
Cornmeal grind affects packing. Coarse grinds vary more by volume, so weigh for cornbread.
How many grams is a cup of cornmeal?
One US cup (240 ml) of cornmeal weighs about 122 grams. Because a cup measures volume rather than weight, that figure is specific to cornmeal and does not transfer to any other ingredient: the same cup holds 125 grams of all-purpose flour and 340 grams of honey.
- 1/4 cup of cornmeal is about 31 grams
- 1/3 cup of cornmeal is about 41 grams
- 1/2 cup of cornmeal is about 61 grams
- 2/3 cup of cornmeal is about 81 grams
- 3/4 cup of cornmeal is about 92 grams
- 1 1/2 cups of cornmeal is about 183 grams
- 2 cups of cornmeal is about 244 grams
- 3 cups of cornmeal is about 366 grams
Working the other way round, 100 grams of cornmeal is about 0.82 cups, and 500 grams is about 4.1 cups.
Does it matter which cup my recipe means?
It does, though less than the ingredient itself. This page uses the US legal cup of 240 ml. An Australian metric cup is 250 ml, so a metric cup of cornmeal comes to about 127 grams, and the old British imperial cup of 284.1 ml holds about 144 grams. See cup sizes by country for every standard side by side.
Frequently asked questions
How many grams is 1 cup of cornmeal?
One US cup of cornmeal is about 122 grams. Grind size shifts this a little, with coarser meal packing more loosely.
Is cornmeal the same as polenta?
Essentially yes. Polenta is usually a medium or coarse cornmeal, and it weighs about the same per cup at around 122 grams.
Why weigh cornmeal for cornbread?
The cornmeal to liquid ratio decides the crumb. Because grinds and brands differ, weighing to 122 grams per cup keeps cornbread reliably tender.
Where this figure comes from
We have not yet found a published reference that states a weight for a cup of cornmeal. The 122 grams on this page follows the calibration the rest of the site is built on, with butter at 227 grams per cup, water at 240, all-purpose flour at 125 and granulated sugar at 200. Treat it as a good working figure rather than a cited one. If you have a better source, tell us and we will check it and credit you.
Published figures for the same ingredient vary between references anyway, because how an ingredient is packed changes what a cup of it weighs. Treat any cup figure as accurate to within a few percent, and weigh on a scale when a recipe is sensitive. Our full approach is on the methodology page.
