Key Facts about Table Salt
Sodium vs. Total Salt
Table salt is roughly 40% sodium and 60% chloride by weight. 1 tsp of salt contains about 2,325 mg of elemental sodium.
Crystal Size Matters
Diamond Crystal kosher salt is almost half as dense as table salt due to hollow flaked crystals. 1 tsp equals only ~2,800 mg.
Culinary Density
Table salt has an average bulk density of 1.217 g/mL, making it roughly 22% denser than water.
How to Convert a Teaspoon of Table Salt to Milligrams
Teaspoons measure volume. Milligrams measure mass. To convert between them you need the substance density.
For Table Salt, the density is approximately 1.217 g/mL. Table salt has a bulk density of ~1.217 g/mL. 1 US tsp = ~5,998 mg.
Formula
mg = tsp × 4.92892 mL × 1.217 g/mL × 1000Example: 1 tsp of Table Salt = 1 × 4.92892 × 1.217 × 1000 = 5,998.5 mg
