The Formula

Salt (grams) = Sodium (mg) / 400 (Since table salt is roughly 40% sodium and 60% chloride)

Variable Definitions

  • Sodium (mg): Pure dietary sodium in milligrams
  • Salt (g): Equivalent weight in grams of Sodium Chloride (table salt)

Converting a 1,500 mg Low-Sodium Guideline to Salt

The American Heart Association recommends a limit of 1,500 mg of sodium for adults with hypertension.

  1. Step 1: Set Sodium = 1,500 mg.
  2. Step 2: Divide by 400 to find salt weight: 1,500 / 400 = 3.75 grams of salt.
  3. Step 3: This translates to slightly less than 3/4 of a teaspoon of total salt per day.
