Sodium to salt converter

Convert milligrams of sodium to grams of salt and back. Edit either side.

Table salt is about 40% sodium, so salt = sodium × 2.5 (1g of salt is about 400mg of sodium). One Saltivate serving, 800mg sodium, is roughly 2g of salt.

Based on table salt being about 40% sodium. Other salts vary slightly.

Constants publishedFree to embed

A unit conversion with no assumptions about you: sodium and salt are two ways of measuring the same thing.

The conversion

Table salt is sodium chloride. Sodium is 39.34% of its mass, from the molar masses of sodium (22.99 g/mol) and sodium chloride (58.44 g/mol).

  • Rounded to 40%, so 1 g salt = 400 mg sodium
  • salt (g) = sodium (mg) / 400
  • sodium (mg) = salt (g) x 400

Why both units exist

United States nutrition labels declare sodium. Most European labels declare salt equivalent.

The same product can show two numbers differing by about 2.5x without either being wrong.

A general population reference, not a personal target.

Limitations 3
  • Rounding 39.34% to 40% understates salt mass by about 1.7%. At 2,300 mg sodium that is about 0.1 g of salt.
  • Sea salt and other unrefined salts vary slightly in sodium by mass because of moisture and trace minerals.
  • This converter does not recommend an intake for you. It converts units only.

How to convert sodium to salt

Table salt is sodium chloride, and it is about 40 percent sodium by weight. To turn sodium into salt, multiply by 2.5. To turn salt into sodium, divide by 2.5, or multiply grams of salt by 400 to get milligrams of sodium. So 1,000mg of sodium is about 2.5g of salt, and a level teaspoon of salt (around 6g) is roughly 2,300mg of sodium.

Nutrition labels measure sodium, but recipes and salt packets talk in salt, which is where the two get mixed up. One Saltivate serving has 800mg of sodium, which is about 2g of salt, the amount that noticeably seasons a drink.

Good to know

Sodium and salt, converted

How do you convert sodium to salt?
Multiply milligrams of sodium by 2.5 to get milligrams of salt, since table salt is about 40 percent sodium. To go the other way, divide salt by 2.5, or multiply grams of salt by 400 to get milligrams of sodium.

How much sodium is in a teaspoon of salt?
A level teaspoon of table salt weighs around 6 grams and contains roughly 2,300mg of sodium, which is the commonly cited daily upper limit on its own.

How much salt is 800mg of sodium?
About 2 grams. One Saltivate serving carries 800mg of sodium, roughly the salt in two-fifths of a teaspoon.

Is sodium the same as salt?
No. Salt is sodium chloride, and sodium makes up about 40 percent of it by weight; the rest is chloride. Nutrition labels measure sodium, not salt.

Salt math, already measured

One Saltivate serving carries 800mg of sodium, about 2g of salt, plus 240mg potassium and 60mg magnesium. Zero sugar, no stevia, HSA/FSA eligible. To size your intake, estimate what you lose in sweat first.
