What is the Salt Converter — Kosher vs Table by Weight?
Salt is the one ingredient where the brand genuinely changes the recipe. A cup of Diamond Crystal kosher salt weighs 135 g, while a cup of Morton kosher weighs 225 g — so a recipe developed with one and cooked with the other is off by two-thirds. This converter takes a volume of the salt a recipe calls for and gives you the matching volume of the salt you actually own, along with the weight both share. Weighing in grams sidesteps the problem entirely, and the gram figure is always shown.
How to use the Salt Converter — Kosher vs Table by Weight
- 1 Enter the amount of salt the recipe calls for, in cups.
- 2 Pick the salt the recipe was written with.
- 3 Pick the salt you actually have in the cupboard.
- 4 Use the converted volume, or the gram weight if you have a scale.
Frequently asked questions
Is Diamond Crystal the same as Morton kosher salt? +
No — and this is the most common salting mistake in American recipes. Morton kosher salt is denser: a cup weighs about 225 g against Diamond Crystal’s 135 g. Substituting one for the other by volume changes the seasoning by roughly two-thirds, so use about 40% less Morton than a Diamond Crystal measurement.
Why not just weigh the salt? +
You should when you can — weight is the only measurement that does not care about crystal shape or packing. The converter always shows the gram figure alongside the volumes for exactly this reason.
How accurate are the results? +
The figures come from standard, tested references (USDA FoodData Central and King Arthur Baking) and are excellent starting points. Ovens, ingredients and equipment vary, so treat the numbers as a reliable guide and adjust to taste and doneness.
Is this calculator free, and does it send my data anywhere? +
