Salt is measured by the spoonful but seasons by weight, and a teaspoon of one salt rarely weighs the same as a teaspoon of another. These figures are the grams per quarter teaspoon from each brand's Nutrition Facts panel — Diamond Crystal kosher 0.7 g, Morton coarse kosher 1.2 g, table salt 1.5 g — so 1 tablespoon of Diamond Crystal kosher salt comes to 8.4 g, which is about 1¾ teaspoons of Morton coarse kosher salt once you measure it out.
How the conversion is worked out
- The grams per teaspoon is the serving size on each brand's Nutrition Facts panel: Diamond Crystal kosher 2.8 g, Morton coarse kosher 4.8 g, table salt 6.0 g.
- Salt is matched by weight, not volume: the same grams of salt, whatever the size of the crystals.
- Diamond Crystal kosher is the lightest, so it takes about twice the volume of table salt to weigh the same.
- Teaspoons and tablespoons are level, not heaped; a tablespoon is three teaspoons and a cup is 48.
- Amounts are rounded to the nearest eighth of a teaspoon; for baking, weigh the grams.
