One tablespoon of cornmeal weighs 8.6 g (spooned and levelled, King Arthur Baking). Cornmeal is a light, coarse-ground grain — much lighter per spoonful than flour, because its large particles leave air gaps between them — and that lightness is why a tablespoon of cornmeal weighs less than a tablespoon of almost any flour. The figure matters when you are dusting a pizza peel, thickening a batter, or making cornbread, where the ratio of cornmeal to flour decides the texture. It also matters for polenta, where a few tablespoons too many turns a creamy porridge into a solid slab. All weights on this page are approximate; coarse and fine cornmeal differ slightly, so verify with a scale when it matters.
How much does 1 tablespoon of cornmeal weigh?
One level tablespoon of cornmeal weighs 8.6 g, spooned and levelled, according to King Arthur Baking. That is the headline number, but a single tablespoon is rarely the whole story — most recipes use several spoonfuls, or a fraction of a cup, so the table below gives the weights you will actually reach for, from a teaspoon up to a full cup. Every figure is derived from the same source value of 138 g per cup, so the whole table is consistent. Treat all of these as approximate: spooned and levelled is a technique, not a machine setting, and two cooks measuring the same ingredient can differ by a gram or two per spoonful. When the recipe matters, weigh the ingredient on a kitchen scale instead.
| Amount | Weight (approx.) |
| --- | --- |
| 1 teaspoon | 2.9 g |
| 1 tablespoon | 8.6 g |
| 2 tablespoons | 17.2 g |
| 3 tablespoons | 25.9 g |
| 1/4 cup (4 tbsp) | 34.5 g |
| 1/2 cup (8 tbsp) | 69 g |
| 3/4 cup (12 tbsp) | 103.5 g |
| 1 cup (16 tbsp) | 138 g |
A useful rule of thumb: there are 3 teaspoons in a tablespoon and 16 tablespoons in a cup, so you can move between any of these measures by multiplying or dividing. If a recipe calls for 2 teaspoons and you only have a tablespoon measure, that is two-thirds of a tablespoon — about 5.8 g. If a recipe calls for a quarter cup and you only have a tablespoon, that is 4 level tablespoons. Keep the tablespoons to grams converter open while you cook and you will never need to do the arithmetic in your head.
Worked examples
Dusting a pizza peel
A pizza maker dusts the peel with 2 tablespoons of cornmeal — about 17 g — to stop the dough sticking. The weight is a useful check because cornmeal's job here is mechanical, not chemical: the coarse grains act like tiny ball bearings under the dough. Too little and the pizza sticks and folds on launch; too much and the crust tastes gritty and the cornmeal burns on the stone, leaving a bitter smell in the oven. Seventeen grams spread thinly across the peel is the right amount for a 30 cm pizza, and weighing it once teaches your hand what the right dusting looks like.
A skillet cornbread
A skillet cornbread uses 1 cup of cornmeal — 16 tablespoons, or about 138 g — mixed with 1 cup of flour. When you halve the recipe for a smaller skillet, that becomes 8 tablespoons, or 69 g. Weighing the cornmeal matters because cornbread texture depends on the cornmeal-to-flour ratio: more cornmeal gives a crumbly, rustic loaf, more flour gives a softer, cake-like one. The recipe's balance is 138 g of cornmeal against 120 g of flour, and a spoon-measured cup of cornmeal can easily be 10 g light or heavy, which shifts the texture noticeably. A scale keeps the ratio exact every time.
Creamy polenta for four
A creamy polenta for four starts with 1 cup of cornmeal — about 138 g — whisked into 4 cups of simmering water or stock. The tablespoon weight is what you need when the recipe is written for a smaller pot: a single serving uses 4 tablespoons, or about 34 g, in 1 cup of liquid. Getting this ratio right is the whole dish — polenta thickens dramatically as it cooks, and a tablespoon too many per serving turns a silky porridge into something you can slice. Weighing the cornmeal also lets you adjust for grind: fine cornmeal absorbs liquid faster than coarse, so the same weight cooks in less time.
How to measure a tablespoon of cornmeal correctly
Cornmeal is measured spooned and levelled, and the grind is the variable that changes the weight. Fine cornmeal packs more densely than coarse, so a level tablespoon of fine cornmeal can weigh 9.5 g while the same spoonful of coarse cornmeal weighs 8 g. The King Arthur figure of 8.6 g per tablespoon is for standard whole cornmeal. Spoon the cornmeal into the tablespoon with a smaller spoon, letting it fall loosely, then sweep a knife across the top. Never dip the tablespoon into the bag — dipping compresses the grains and adds up to 20 percent. For polenta and cornbread, where the cornmeal is measured in cups, weighing is far more reliable: tare the bowl, pour the cornmeal in, and stop at the target weight. Store cornmeal in an airtight container, and refrigerate whole-grain cornmeal, because its oils can turn rancid at room temperature.
When the weight matters most
Cornmeal's tablespoon weight matters most in cornbread and polenta, where it is the main ingredient rather than a minor addition. In cornbread, the ratio of cornmeal to flour and liquid decides whether the loaf is crumbly or tender, and a 10 g error in a cup of cornmeal shifts that ratio enough to notice. In polenta, the ratio of cornmeal to liquid is even more critical — the dish goes from soup to sliceable solid across a narrow range, and a tablespoon too many per serving is the difference between the two. The weight also matters for dusting and breading, where cornmeal is used by the tablespoon and the amount decides whether a coating is crisp or gritty. And for anyone tracking nutrition, cornmeal's lightness per tablespoon is deceptive: it is still about 30 calories per tablespoon, and a cup of it carries the same energy as a cup of flour despite weighing less.
Common mistakes to avoid
The most common mistake is treating all cornmeal as the same. Fine, medium and coarse grinds weigh differently per tablespoon and cook differently — fine cornmeal makes a smooth polenta in 10 minutes, coarse cornmeal needs 40 minutes and constant stirring. Always check the grind your recipe expects. The second mistake is confusing cornmeal with cornstarch: cornstarch weighs 7 g per tablespoon and is a pure thickener, while cornmeal is a grain with texture and flavour, and swapping them ruins a recipe. The third mistake is storing whole-grain cornmeal at room temperature for months — its oils go rancid, and rancid cornmeal tastes bitter and soapy. Refrigerate it. Finally, do not add cornmeal to boiling liquid all at once: it clumps instantly. Rain it in slowly while whisking, or mix it with a little cold water first.
Frequently asked questions
How many grams is 1 tablespoon of cornmeal?
One tablespoon of cornmeal weighs 8.6 g, spooned and levelled, according to King Arthur Baking. One teaspoon weighs about 2.9 g. These are approximate weights — fine cornmeal packs more densely than coarse, so weigh it for the most accurate result.
How many tablespoons of cornmeal are in 100 g?
There are about 12 tablespoons in 100 g of cornmeal (100 divided by 8.6 is 11.6). A standard 500 g bag holds about 58 tablespoons, which is roughly 3.5 cups.
Is cornmeal the same as polenta?
Almost. Polenta is a dish made from cornmeal, and the cornmeal sold as polenta is usually a medium or coarse grind. You can use regular cornmeal to make polenta, but fine cornmeal cooks faster and gives a smoother result, while coarse cornmeal needs longer cooking and gives a more rustic texture.
Can I use cornmeal instead of flour?
Not 1:1. Cornmeal has no gluten, so it cannot replace flour in bread or cakes — the result would crumble. It works as a partial replacement in cornbread and muffins, where its texture is wanted, and as a coating or dusting where flour would turn gummy.
How long does cornmeal last?
Degerminated cornmeal keeps for about 1 year in a cool, dry cupboard. Whole-grain cornmeal should be refrigerated and used within 6 months, because its oils turn rancid. Discard cornmeal that smells bitter or musty.
