In short
One us cup of table salt is 273 gram. Going the other way, one gram is 0.0036630037 us cup. That works out at 2 us cup = 546 gram and 4 = 1092. The figure comes from table salt weighing 273 g per US cup — a generic cups-to-grams converter assumes water and will give you the wrong answer here, because volume to weight depends entirely on what is in the cup.

About the Cups to Grams — Table Salt
This is the single most dangerous cup measurement in cooking. Fine table salt is dense and packs tightly; the same cup of flaky sea salt weighs less than half as much, and Diamond Crystal kosher salt about half. A recipe that says "1 tsp salt" without naming the type can be out by a factor of two. Table salt 273 g per cup, Morton kosher about 218 g, Diamond Crystal about 137 g. The figure this page works from is 273 g per US cup, the spooned-and-levelled weight recorded by King Arthur Baking and the USDA food database. Converting us cup to gram for table salt, the amounts that come up most often are: 1/4 us cup = 68.3 gram; 1/3 us cup = 91 gram; 1/2 us cup = 137 gram; 2/3 us cup = 182 gram; 3/4 us cup = 205 gram; 1 us cup = 273 gram; 1 1/2 us cup = 41 gram; 2 us cup = 546 gram; 3 us cup = 819 gram.
What people use it for
- Following a US recipe with a kitchen scale instead of cup measures.
- Scaling a recipe up or down without compounding measuring error.
- Converting a European recipe written in grams into cups.

The maths behind it
This tool uses gram = us cup × 273, derived from table salt weighing 273 g per US cup. Every intermediate value is shown on screen, so the result can be checked by hand.
This is the single most dangerous cup measurement in cooking. Fine table salt is dense and packs tightly; the same cup of flaky sea salt weighs less than half as much, and Diamond Crystal kosher salt about half. A recipe that says "1 tsp salt" without naming the type can be out by a factor of two.
Where this tool stops
Volume-to-weight conversion is inherently approximate. Humidity, brand, how finely something is milled and how long it has sat in the cupboard all shift the figure by a few per cent.
Frequently asked questions
Why does my food taste too salty when I follow US recipes?
Because many US recipes assume Diamond Crystal kosher salt, which is roughly half the density of table salt. Swapping table salt in by volume doubles the sodium. Weigh salt, or halve the volume when substituting fine table salt for kosher.
Why does a cup of table salt not weigh the same as a cup of water?
Because a cup measures volume and a scale measures weight, and the two only agree for water. Table salt has its own density — 273 g per US cup — so any generic volume converter gives the wrong answer here.
How much does the way I fill the cup matter?
Not much for table salt, whose fine uniform crystals settle consistently to about 273 g per cup. The far bigger trap with salt is the TYPE: a cup of coarse kosher or flaky sea salt weighs dramatically less for the same volume, so swapping one for another by cup rather than by weight is how a dish ends up over- or under-seasoned.
Is a US cup the same as a UK or metric cup?
No. A US cup is 236.6 ml, a metric cup is 250 ml and an old UK cup is 284 ml. These pages use the US cup, because that is what US recipes mean.
Are there any usage caps on the Cups to Grams — Table Salt?
No charge and no sign-up. There is no free tier to run out of because there is no paid tier — inputtesthub.com is funded by advertising rather than by metering the tool.
Can you see what I put into this tool?
No. The Cups to Grams — Table Salt runs entirely in your browser using JavaScript. Because the work happens locally, the tool also keeps working if your connection drops, and closing the tab is all it takes to discard everything.
Can I check the maths myself?
It uses gram = us cup × 273, derived from table salt weighing 273 g per US cup. The full working is printed under the result, so you can follow every step rather than trusting a black box.
Can you show an example?
Enter 2 us cup of table salt and the Cups to Grams — Table Salt returns 546 gram.
What do people use the Cups to Grams — Table Salt for most?
In practice it gets used for three things: following a US recipe with a kitchen scale instead of cup measures. Scaling a recipe up or down without compounding measuring error. Converting a European recipe written in grams into cups. It is built for exactly those cases rather than being a general-purpose tool with this bolted on.
Is there anything the Cups to Grams — Table Salt cannot do?
Volume-to-weight conversion is inherently approximate. Humidity, brand, how finely something is milled and how long it has sat in the cupboard all shift the figure by a few per cent. Knowing where a tool stops being trustworthy matters more than the cases where it works.
What figures does the Cups to Grams — Table Salt work from?
1 US cup of table salt is 273 g. 1 US cup is 273 Gram. 1 Gram is 0.0036630037 US cup. These are printed on the page itself, so you do not have to take them on trust.
How precise is the result?
The calculation runs in double precision and the result is shown to ten significant figures, so converting a value and converting it back returns the original. What is displayed is rounded for readability; what is copied is not.
