Cups to grams: table salt

A US cup of table salt weighs roughly 292 grams, or 10.30 ounces. By volume, salts differ enormously: a cup of table salt weighs twice what a cup of Diamond Crystal kosher salt does.

Amount in US cups = 1
Or a weight to convert back = 100
Grams per cup used = 292 = 292
Weight = 1 * 292 = 292
Weight in ounces = 292 / 28.349523125 = 10.3
Tablespoons = 1 * 16 = 16
Teaspoons = 1 * 48 = 48
Volume = 1 * 236.5882365 = 236.588
Cups in the weight you entered = 292 > 0 ? 100 / 292 : 0 = 0.342 466
Tablespoons in that weight = 0.342 466 * 16 = 5.479 45
Implied bulk density = 292 / 236.5882365 = 1.234 21

Values are shown to six significant figures here; the arithmetic itself runs on exact fractions and is only rounded where a number is printed.

The formula

grams = cups x grams per cup
1 US cup = 16 tablespoons = 48 teaspoons = 236.588 236 5 mL exactly
1 ounce = 28.349 523 125 g exactly

Cup figures assume the spoon-and-level convention: fluff the ingredient, spoon it into the cup and sweep the top flat. Dipping the cup straight into the bag packs in up to 20% more.

The volume conversions on this page are exact by definition. Only the grams-per-cup figure is a measured convention, and it is stated above so you can substitute your own.

By volume, salts differ enormously: a cup of table salt weighs twice what a cup of Diamond Crystal kosher salt does.

Frequently asked

How many grams are in a cup of table salt?

About 292 g, using the spoon-and-level convention for a US cup.

How many grams are in a tablespoon of table salt?

About 18.25 g, since a tablespoon is exactly one sixteenth of a US cup.

Is a US cup the same as a metric cup?

No. A US cup is 236.588 mL, a metric cup is 250 mL and an imperial cup is 284.13 mL. A recipe that says "cup" without qualification almost always means the US one.

Where the numbers come from

Volume relationships follow the US customary definitions; the grams-per-cup figure is the widely published spoon-and-level convention for this ingredient.
