Sodium — Quick answer

Salt is about 40% sodium, so salt grams ≈ sodium grams × 2.5.

salt(g) = sodium(mg) ÷ 1000 × 2.5  ·  limit 2300 mg · ideal 1500 mg

Worked example: 2300 mg sodium ≈ 5.75 g salt ≈ 1 tsp.

ℹ️ Salt is ~40% sodium: salt(g) = sodium(g) × 2.5. FDA limit 2300 mg/day; AHA ideal 1500 mg. General info, not medical advice.

Table salt is sodium chloride, about 40% sodium by weight — so salt (g) ≈ sodium (g) × 2.5. This calculator converts between the two, shows the teaspoons of salt, and compares your intake to the 2300 mg daily limit and the 1500 mg ideal.

Sodium, salt & limits

Conversion
salt(g) = sodium(mg) ÷ 1000 × 2.5  ·  sodium(mg) = salt(g) × 400

Because sodium is only part of salt, a small amount of salt carries a lot of sodium: one level teaspoon (≈ 5.7 g) holds about 2300 mg of sodium — the whole daily limit. The FDA Daily Value caps sodium at 2300 mg, and the American Heart Association suggests aiming for 1500 mg. Most dietary sodium comes from packaged and restaurant foods rather than the salt shaker.

Worked examples

3400 mg sodium (US average):

8.5 g salt
3.4 × 2.5 = 8.5 g · ÷ 2300 = 148% of the limit

2000 mg sodium:

5.0 g salt
87% of the 2300 mg limit, but 133% of the 1500 mg ideal

6 g of salt:

2400 mg sodium
6 × 400 = 2400 mg → just over the 2300 mg limit

Cutting from the 3400 mg average to the 2300 mg limit means removing roughly 2.75 g of salt — about half a teaspoon — mostly by choosing lower-sodium packaged foods and reading nutrition labels.

Frequently Asked Questions

How much sodium per day?

FDA limit 2300 mg; AHA ideal 1500 mg. About 1 tsp of salt = 2300 mg.

How do I convert sodium to salt?

Salt(g) ≈ sodium(g) × 2.5. 2300 mg sodium ≈ 5.75 g salt.

How many teaspoons is too much?

~1 tsp of salt holds 2300 mg sodium — the daily upper limit.

What is the average intake?

~3400 mg/day in the US — 8.5 g salt, about 148% of the limit.

Is this medical advice?

No — general info. Follow your clinician's target if you have BP, heart or kidney conditions.
