Salt Type Conversion Calculator
Different salts have different crystal sizes, so a teaspoon of flaky kosher salt holds far less salt than a teaspoon of fine table salt. Enter an amount and the two salt types to get the equivalent that keeps the same saltiness.
How to use the salt conversion calculator
- Enter the amount in teaspoons that your recipe lists.
- Choose the salt type the recipe used and the salt type you have.
- Read the equivalent teaspoons and the weight in grams.
Examples
Table to Diamond Crystal
1 tsp table salt (6 g)
about 2.14 tsp Diamond Crystal kosher
Diamond Crystal to table
1 tsp Diamond Crystal (2.8 g)
about 0.47 tsp table salt
Frequently asked questions
Why is salt not a one to one swap by volume?
Because crystal size and density differ. A level teaspoon of fine table salt weighs about 6 grams, while the same teaspoon of flaky Diamond Crystal kosher salt is only about 2.8 grams. Swapping by volume can leave a dish far too salty or flat.
What densities does this calculator use?
It uses common kitchen approximations per level teaspoon: table salt 6 g, Morton kosher 4.8 g, Diamond Crystal kosher 2.8 g, and fine sea salt 5.5 g. These are typical reference values, though brands and packing vary slightly.
How does the conversion keep the saltiness the same?
It converts your teaspoons to grams using the source salt density, then divides by the target salt density to get teaspoons. Holding the weight of salt constant keeps the seasoning level the same between salt types.
Why does so much kosher salt replace table salt?
Flaky kosher salt is much less dense, so it takes more volume to reach the same weight. Replacing 1 teaspoon of table salt needs roughly 2 teaspoons of Diamond Crystal kosher salt to match the saltiness.
Should I just weigh salt instead?
Weighing in grams is the most reliable method and removes density differences entirely. This calculator also reports the gram weight, so you can either measure by volume or switch to a scale for precision.
