One US cup of kosher salt weighs about 240 grams. That single number is what makes this conversion possible, and it is why baking by weight is more reliable than baking by volume.
Flake size varies by brand, so this is the most variable entry here. Volume measures depend on how the ingredient is packed into the cup, while a gram is a gram no matter how you scoop it.
Enter your amount above to convert it. The table below covers the fractions recipes actually call for, including thirds and eighths of a cup.
The kosher Salt gram to cup table below carries 11 pre-computed rows, from 25 g to 1000 g, so a figure can be checked against this page without typing anything into it. Nothing has to be entered to see it work: the default for grams of kosher salt is 240 g, and the output recomputes the moment that changes. Every symbol in the formula — 3 of them (cups, 240, grams) — is defined above rather than left as notation to decode.

The formula
cups- Volume of kosher salt in US cups
240- Grams in one US cup of kosher salt
grams- Weight of the ingredient
How it works, step by step
- Enter your quantity of kosher salt.
- The tool applies the density of 240 g per US cup.
- The converted figure appears immediately, along with an ounce equivalent.
- Use the table for common recipe fractions without typing anything.
Worked examples
A standard single batch
If a recipe lists 480 g of kosher salt, that is 2 cups. Weighing is faster than levelling two separate cups.
Scaling a recipe by half
120 g of kosher salt is half a cup, which is the amount most often halved when scaling a recipe down.
Checking the 150 g row
The reference table lists Grams = 150 g, giving Cups: 0.62 cups, Ounces: 5.3 oz. Entering that above should reproduce the same figures — if it does not, the input is being read differently to the way the table assumes.
Frequently asked questions
How many grams are in a cup of kosher salt?
About 240 grams for a US cup. Flake size varies by brand, so this is the most variable entry here.
How many grams are in a tablespoon of kosher salt?
A US tablespoon is one sixteenth of a cup, so about 15.0 grams.
Why do different sources give different gram values?
Because volume measuring is genuinely imprecise. How you fill the cup changes the weight, sometimes by 20% or more for flours and powders. Published values assume a specific method — usually spooned and levelled — and this page uses that convention.
Should I bake by weight or volume?
By weight whenever a scale is available. It is more repeatable, faster with fewer dishes, and it is the reason professional recipes are written in grams.
How precise is the volume in cups?
Internally the maths runs at full double precision and the display keeps the significant figures that carry information, dropping the digits that are only rounding noise. Rounding happens at the display step alone, so nothing accumulates error as you change the input. The figure is reported in cups.
What formula does the Kosher Salt: Grams to Cups Converter use?
It computes cups = grams ÷ 240, where cups is volume of kosher salt in US cups; 240 is grams in one US cup of kosher salt; grams is weight of the ingredient. The same expression is printed on the page above the inputs, so the result can be reproduced by hand or in a spreadsheet.
