Salt: Cups to Grams
One US cup (240 ml) of salt weighs 273 grams; half a cup weighs 137 grams. A quarter cup is 68.3 grams, a tablespoon is 17.1 grams and a teaspoon is 5.69 grams. A cup measures volume, not weight, so these numbers are for salt only: a cup of all-purpose flour weighs 125 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 salt weighs about 9.63 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 salt
Fine table salt is dense and packs tightly, so one US cup weighs about 273 grams. This is the ingredient where cup and spoon measures cause the most trouble, because coarse kosher and flaky sea salts are far less dense than fine table salt. A cup of flaky salt might weigh half as much. If a recipe specifies a salt type, matching it or weighing in grams is the only way to season accurately.
Salt density varies hugely by grain. A cup of flaky salt weighs far less than fine table salt.
How many grams is a cup of salt?
One US cup (240 ml) of salt weighs about 273 grams. Because a cup measures volume rather than weight, that figure is specific to salt 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 salt is about 68 grams
- 1/3 cup of salt is about 91 grams
- 1/2 cup of salt is about 137 grams
- 2/3 cup of salt is about 182 grams
- 3/4 cup of salt is about 205 grams
- 1 1/2 cups of salt is about 410 grams
- 2 cups of salt is about 546 grams
- 3 cups of salt is about 819 grams
Working the other way round, 100 grams of salt is about 0.366 cups, and 500 grams is about 1.83 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 salt comes to about 284 grams, and the old British imperial cup of 284.1 ml holds about 323 grams. See cup sizes by country for every standard side by side.
Frequently asked questions
How many grams is 1 cup of table salt?
One US cup of fine table salt is about 273 grams. Fine grains pack tightly, making table salt one of the denser dry ingredients.
Why is kosher salt lighter than table salt?
Kosher salt has large, flaky crystals that trap air, so a cup weighs much less than fine table salt. Always match the salt type a recipe calls for, or weigh it.
How many grams is a teaspoon of table salt?
About 5.7 grams. Because table salt is dense, a level teaspoon carries a fair amount of weight compared with coarse salts.
Where this figure comes from
We have not yet found a published reference that states a weight for a cup of salt. The 273 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.
