Daily Sodium Calculator
Enter milligrams and a multiplier. 500 × 3 gives 1500. 200 × 2 gives 400. 800 × 1 gives 800. The result has no unit. That is a product, not a guideline limit.

Enter data and click Calculate.
Not a clinic verdict and not a WHO limit. The calculator multiplies two fields. The result label may say limit; the code still prints the product.
How it works
Daily sodium in this calculator is milligrams times a factor. 500 × 3 = 1500. The result is 1500, with no mg and no word limit. 200 × 2 = 400. 800 × 1 = 800. No table threshold sits in the formula.
Field a is a serving in mg. Field b is the factor: three servings, two meals, one product. 500 and 3 give 1500 because that is how the code multiplies. It does not check whether 1500 is „too much”.
WHO and national guidance often sit near 2000 mg sodium per day, sometimes lower. This calculator does not insert that. You compare 1500 with 2000 yourself. 800 × 1 stays 800 even when the label talks about a limit.
Table salt is not this field. 1 g of salt is about 400 mg sodium, but there is no NaCl converter here. You already enter sodium in mg, then times b.
Enter mg, enter the factor, then Calculate. A comma in 500.5 parses. Zero times anything is 0. A sum estimate, not a clinic diet.
500 × 3 gives 1500. 200 × 2 gives 400. 800 × 1 gives 800. The result is a bare number, as a bare result string.
result = a × b (bare number, no unit)
Daily sodium is a × b. 500 × 3 shows 1500, with no unit. This is not a WHO limit.

Common questions
How much sodium at 500 mg and factor 3?
1500. The calculator shows String(1500), with no mg.
Is 1500 a WHO limit?
No. WHO is often about 2000 mg per day. Here only the product 500 × 3.
What about 200 and 2?
400. Again a bare number.
What about 800 and 1?
800. Factor 1 leaves the same entry.
Why is there no mg on the result?
That is how the script is written: the result string = String(result). No unit.
Does the calculator convert salt to sodium?
No. You already enter sodium in mg. 1 g of salt is not this field.
Does the limit label change the formula?
No. The label may say limit; the code multiplies a × b.
Is 1500 too much?
The calculator does not judge that. Not a clinic verdict.
Does a comma in 500.5 work?
Yes. 500.5 × 2 gives 1001.
How do I add sodium from several servings?
Enter mg from the label and a multiplier (number of servings or same-value items). 500 × 3 = 1500. 200 × 2 = 400. 800 × 1 = 800. The calculator does not add separate food-database rows.
Does the result compare to the WHO 2000 mg limit?
No. This calculator only multiplies. It does not show a percent of a limit and does not convert sodium to salt (g). Limits and salt conversion live elsewhere.
Is this a salt-to-sodium converter?
No. Inputs are already milligrams of sodium. If the label lists salt in grams, convert first (about 1 g salt ≈ 400 mg sodium), then enter mg here.
Is 1500 mg dietitian advice?
No. It is the product of the numbers you enter. With hypertension, kidney disease, or a clinical diet, a clinician sets the target — not this calculator.
