🧂 Sodium in Salt Calculator
Convert between table salt (sodium chloride) and its sodium content, using the standard chemistry ratio that sodium makes up about 39.3% of salt’s weight.
Salt vs. sodium
Table salt (sodium chloride, NaCl) is not pure sodium. By molecular weight, sodium accounts for about 39.3% of salt, with the rest being chloride. This distinction matters because nutrition labels and health guidelines track sodium, not total salt weight.
The formula
This calculator multiplies the amount of salt (in grams) by 0.393 to estimate the sodium content in milligrams. For reference, it also compares your entry to one teaspoon of table salt, which contains roughly 5.69 grams of salt and about 2,300 mg of sodium, close to common daily sodium guidance limits.
Actual values can vary slightly by salt type (e.g., sea salt vs. table salt) and grain size. This tool is for general educational and dietary planning purposes and is not a substitute for professional medical or nutritional advice.
