Where the figure comes from
The weight on this page is from the King Arthur Baking ingredient weight chart, which lists cornmeal as 1 cup = 138 g. Scaled to one US cup of 236.59 ml, that is 138 g. Every other number on the page is that figure multiplied or divided.
The chart entry is for: Whole cornmeal.
grams = cups x 138
cups = grams / 138
For example, 1 1/2 cups of cornmeal is 1.5 x 138 = 207 g, and 300 g is 300 / 138 = 2.17 cups.
How cornmeal compares by the cup
A cup measures volume, so its weight depends on what fills it. A cup of cornmeal is 39.2 percent lighter than a cup of water (227 g). It is 15 percent heavier than a cup of all-purpose flour (120 g).
Other grains and starches from the same chart, per US cup:
- Long grain rice, dry: 198 g, 60 g more than cornmeal
- Cornstarch: 112 g, 26 g less than cornmeal
- Rolled oats: 89 g, 49 g less than cornmeal
US cup or metric cup
A US cup is 236.59 ml and a metric cup, used in Australia, New Zealand and Canada, is 250 ml. The metric cup is 5.7 percent larger, so it holds 146 g of cornmeal against 138 g. Tablespoons and teaspoons on this page are US spoons. The calculator above has a switch for the cup size.
