Low-Sodium Conversion Calculator
Convert between milligrams of sodium, grams of salt, teaspoons of salt, and other sodium measurements for low-sodium diets and recipes.
Step 1: Enter Sodium Amount
Understanding Sodium & Salt
Salt (NaCl) is approximately 40% sodium and 60% chloride by weight. 1 gram of salt contains about 400 mg of sodium. Health guidelines recommend less than 2,300 mg sodium per day (about 1 teaspoon of salt).
Step 2: Calculation Options
Conversion Formulas
Sodium to Salt: Salt (g) = Sodium (mg) ÷ 400
Salt to Sodium: Sodium (mg) = Salt (g) × 400
Teaspoon to Salt: 1 tsp salt ≈ 5.69 g ≈ 2,300 mg sodium
mmol to mg: 1 mmol Na = 23 mg Na

Sodium Conversion Formulas
Sodium to Salt Conversion
Formula: Salt (grams) = Sodium (mg) ÷ 400
Example: 1,000 mg sodium ÷ 400 = 2.5 g salt
Why 400? Salt is approximately 40% sodium by weight, so 1 g salt ≈ 400 mg sodium.
Salt to Sodium Conversion
Formula: Sodium (mg) = Salt (grams) × 400
Example: 5 g salt × 400 = 2,000 mg sodium
Note: This is approximate; actual sodium content varies slightly by salt type.
Teaspoon Conversions
Formula: 1 teaspoon salt ≈ 5.69 grams ≈ 2,300 mg sodium
Conversion: Teaspoons = Salt (grams) ÷ 5.69
Example: 2.5 g salt ÷ 5.69 = 0.44 teaspoons
Millimole Conversion
Formula: 1 mmol sodium = 23 mg sodium
Medical Use: Millimoles are used in medical contexts for electrolyte balance.
Example: 100 mg sodium = 100 ÷ 23 ≈ 4.35 mmol sodium
