Teaspoon values use your selected grams-per-teaspoon assumption. A common kitchen estimate is 6 grams per teaspoon of table salt.

Example Data Table

Food or Recipe	Salt Added	Servings	Total Sodium	Per Serving Sodium	Daily Limit %
Vegetable Soup	5 g	4	1,967 mg	491.75 mg	24.59%
Grilled Chicken Rub	2 tsp	6	4,720.8 mg	786.8 mg	39.34%
Pasta Sauce	3 g	3	1,180.2 mg	393.4 mg	19.67%
Homemade Bread	8 g	12	3,147.2 mg	262.27 mg	13.11%

These examples assume pure salt conversion and a daily sodium limit of 2,000 mg. Actual food labels may differ due to recipe ingredients and rounding rules.

Formula Used

Salt to Sodium: Sodium = Salt × 0.3934

Sodium to Salt: Salt = Sodium ÷ 0.3934

Per Serving Sodium: Total Sodium ÷ Servings

Daily Limit Percentage: (Per Serving Sodium ÷ Daily Limit) × 100

Teaspoon Estimate: Salt in tsp = Salt grams ÷ grams per teaspoon

The 0.3934 factor comes from sodium chloride composition. Pure salt contains about 39.34% sodium by weight, while the rest is chloride.

Teaspoon conversions are approximate because grain size and salt type can vary. This calculator lets you set grams per teaspoon for better kitchen estimates.

FAQs

1. Why convert salt to sodium?

Nutrition labels often list sodium, while recipes often list salt. Converting helps you compare cooking amounts with sodium targets, label rules, and health guidance.

2. Is salt the same as sodium?

No. Table salt is sodium chloride. Sodium is only one part of salt, which is why the sodium value is lower than the salt weight.

3. Why is the factor 0.3934 used?

That value reflects sodium’s share of the molecular weight of sodium chloride. It is the standard weight-based conversion factor for pure salt.

4. Are teaspoon results exact?

No. Teaspoon values are kitchen estimates. Fine salt, kosher salt, and sea salt can weigh differently, so adjusting grams per teaspoon improves accuracy.

5. Can I use this for food labels?

Yes, for planning and estimation. Final label values may differ because of rounding rules, added ingredients, moisture changes, and laboratory testing methods.

6. What daily sodium limit should I enter?

A common reference is 2,000 mg or 2,300 mg daily, but your needs may differ. Use the goal recommended by your clinician or diet plan.

7. Can I reverse the calculation?

Yes. Switch the mode to sodium-to-salt when you already know sodium and want the equivalent salt amount for recipes or comparisons.

8. Does this include sodium from other ingredients?

No. This tool converts the entered salt or sodium amount only. Sodium from broth, sauces, baking powder, cheese, or packaged ingredients must be added separately.
