How many grams are in 1 cup of cornmeal?

One cup of cornmeal weighs about 150 grams, spooned and leveled. This figure matches the value published in King Arthur Baking's ingredient weight chart for plain yellow cornmeal.

Is cornmeal the same weight per cup as wheat flour?

No. Cornmeal is heavier than all-purpose flour by volume, about 150 g per cup versus roughly 120 to 125 g per cup for flour, because cornmeal's coarser, denser granules pack more mass into the same space.

Does the spoon-and-level method matter for this conversion?

Yes. The 150 g per cup figure assumes spooning cornmeal into the cup and leveling it off, rather than scooping directly from the bag or container, which packs the grains tighter and adds extra weight.

Does fine versus coarse ground cornmeal change the weight?

Slightly. Finely ground cornmeal packs a bit more densely than coarse or stone-ground cornmeal, so actual weight can vary by up to 10 grams per cup depending on the grind. Weigh your specific brand for precise polenta.

Is it better to measure cornmeal by weight or by cups?

By weight. Cornmeal settles and packs unevenly in a cup depending on scooping technique, while a gram measurement stays consistent, which matters most for hydration-sensitive batters like cornbread.

How many grams is 1/3 cup of cornmeal?

One-third cup of cornmeal is about 50 grams, based on the 150 g per cup density used throughout this tool.
