Sodium and table salt equivalent

Use sodium per serving and the number of servings eaten to estimate total sodium and ordinary table salt equivalent.

Start with your own numbers

Editable example

An example is filled in. Replace it with your own data to calculate.

Read sodium in milligrams per serving, then enter the number eaten. Check the number of servings on the package.

Read sodium in milligrams for one serving from the package. Do not assume one package is one serving.
For a two-serving package, eating half is one serving. Enter zero only when none was eaten.

Example result

Approximate table salt equivalent

1.5g

Ordinary table salt equivalent is an approximation, not the amount of added salt or total daily sodium.

Sodium consumed600 Milligrams

Worked steps

  1. 400 × 1.5 = 600 mg
  2. 600 ÷ 400 = 1.5 g

Total sodium = sodium per serving times servings eaten; approximate ordinary table salt equivalent in grams = sodium in milligrams divided by 400. Check whether the label describes one serving, 100 g or the whole package, and use the amount eaten. Enter zero only when known. This is equivalent sodium in ordinary table salt, not the amount actually added; other ingredients and seasonings also contain sodium. Low-sodium salt has a different composition. This is not total daily intake, dietary advice or diagnosis; consult a health professional about individual restrictions.

Method and scope

This approximates ordinary table salt with 400 mg sodium per gram. It is an equivalent, not the amount of salt added.

Sodium also comes from ingredients and other additives. Lower-sodium salts have different composition; this is not daily intake advice or a medical diagnosis.

What this tool does

Convert the sodium consumed from a labeled food into an approximate ordinary table salt equivalent for easier comparison.

What to enter

Enter sodium in milligrams per labeled serving and the number of servings actually eaten. Check how many servings are in the package.

How it works

Multiply sodium per serving by the number eaten. Divide the total milligrams of sodium by 400 to get grams of ordinary table salt equivalent.

Worked example

A label lists 400 mg sodium per serving. Eating 1.5 servings gives 600 mg sodium, equivalent to approximately 1.5 g ordinary table salt.

Understanding the result

This is an equivalent amount of ordinary table salt, not a claim that the food contains that much added salt. Labels may be rounded.

Limits

Sodium can come from ingredients and other additives. Low-sodium salt has different composition. This is not daily intake or medical advice.
