Salt Grams to Cups

1 US cup of table salt weighs 288 grams. Salt is almost never measured by the cup, so the figure most people actually need is the teaspoon: 6 grams.

Use the converter and charts below for fine table salt, levelled.

Table Salt Grams to Cups Chart

Divide the gram amount by 288 to calculate US cups. The practical fraction is a measuring aid, not a replacement for the exact gram weight.

How to Measure Table Salt

Use measuring spoons, not cups. Salt is dense enough that a cup measurement is rarely meaningful in a recipe, and small errors at teaspoon scale matter far more than the same proportional error in flour.

Grams = cups × 288

One cup is 288 grams, one-half cup is about 144 grams and one-quarter cup is about 72 grams.

Common uses

  • Oatmeal and overnight oats
  • Granola
  • Cookies and crumble toppings

Salt Types: Why Kosher Salt Is Not Table Salt

This is the single most consequential substitution in the kitchen. Crystal size changes the weight of a spoonful dramatically, and recipes rarely say which salt they mean.

Type Grams per US cup What changes
Table salt, fine 288 g The reference on this page. 6 g per teaspoon.
Morton kosher salt 240 g About 5 g per teaspoon.
Diamond Crystal kosher salt 144 g About 3 g per teaspoon, half of table salt.
Fine sea salt 288 g Matches table salt closely.
Flaky sea salt 120 g Large flat crystals, mostly air.

A teaspoon of Diamond Crystal kosher salt weighs half what a teaspoon of table salt weighs. Swapping one for another by volume either halves or doubles the salt, which is the difference between seasoned and inedible.

Comparison figures are typical published US baking references. Only the table salt, fine value above is part of this site's sourced dataset.

Why the Cup Weight Matters

Kosher and flaky salts weigh far less per cup because the crystals are larger. The value on this page names the exact product state it applies to, so you can check it against your own ingredient rather than trusting a bare number.

The converter does not assume that every cup weighs 237 or 250 grams. It uses the documented value for the exact ingredient and state selected.

If a product label or recipe publisher supplies a different gram weight for one cup, follow that recipe-specific value for the closest match to the original testing.

Method and source

How this conversion was checked

This page uses 288 grams per US cup for fine table salt, levelled. Kosher and flaky salts weigh far less per cup because the crystals are larger.
