About the Sodium in Salt Calculator
Salt and sodium are often used interchangeably in everyday language, but they are chemically distinct. Table salt is sodium chloride (NaCl), and sodium is only one of its two constituent elements. Because chlorine is heavier than sodium, salt contains less sodium by mass than most people assume: approximately 39.3% of the weight of table salt is elemental sodium, with the remaining 60.7% being chloride. This means that one teaspoon of table salt (approximately 5 grams) contains roughly 1,965 milligrams of sodium — nearly the entire daily recommended intake for many adults.
Different types of salt vary slightly in their sodium content. Sea salt and table salt have very similar sodium percentages because both are essentially sodium chloride; the differences lie in trace mineral content, texture, and flavour rather than sodium density. Sea salt typically contains about 38.5% sodium by weight. Kosher salt, which comes in a coarse flake form designed for drawing moisture from meat, has a lower apparent density per volume than table salt, but by weight its sodium content is approximately 35–37% — slightly lower than table salt because of its crystalline structure and the inclusion of some potassium chloride in some brands. Pink Himalayan salt is mined rock salt from the Punjab region of Pakistan. It contains over 98% sodium chloride, plus trace amounts of iron oxide (which gives it the pink colour) and around 80 other minerals. Its sodium content by weight is approximately 36–38%.
Health guidelines from the World Health Organization (WHO) recommend a daily sodium intake of less than 2,000 mg, while the US Dietary Guidelines and American Heart Association suggest no more than 2,300 mg per day for healthy adults, with a further reduction to 1,500 mg recommended for individuals with hypertension, diabetes, or chronic kidney disease. Most people in high-income countries consume significantly more than this — estimates suggest 3,400 mg/day in the United States, primarily from processed and restaurant foods.
High sodium intake is a major modifiable risk factor for hypertension (high blood pressure), which in turn is the leading cause of stroke, heart attack, and kidney disease worldwide. Even modest reductions in dietary sodium — a decrease of 400–800 mg per day — have been shown in clinical trials to produce meaningful blood pressure reductions, particularly in hypertensive individuals. The sodium in salt calculator helps you quantify the sodium contribution of the salt you add during cooking or at the table, which is a meaningful but often underappreciated fraction of total daily intake.
Note that the sodium in salt added at the table and during cooking typically accounts for only about 10–15% of total dietary sodium in Western diets. The majority comes from processed foods, bread, cured meats, and restaurant meals. Reducing sodium intake therefore requires attention to food labels and food choices, not just the salt shaker.

| Salt Input | Sodium (mg) | Daily limit context |
|---|---|---|
| 5 g Table Salt, limit 2300 mg | 1965 mg | One teaspoon of table salt uses 85% of the 2300 mg daily limit — more than most people realise. |
| 2 g Sea Salt, limit 2000 mg | 770 mg | A light seasoning of sea salt at 2 g is still 38.5% of a 2000 mg WHO daily limit. |
| 8 g Kosher Salt, limit 2300 mg | 2800 mg | 8 g of kosher salt — typical for brining meat — exceeds the 2300 mg daily limit by 500 mg, before any sodium from the food itself. |
| 3 g Pink Himalayan Salt, limit 1500 mg | 1080 mg | 3 g of Himalayan salt equals 72% of the 1500 mg low-sodium target recommended for people with hypertension. |
How to use this calculator
- Enter the amount of salt in grams. Use a kitchen scale for accuracy — one level teaspoon of fine table salt weighs approximately 6 g.
- Select the salt type from the dropdown to apply the correct sodium percentage for that variety.
- Optionally enter your daily sodium limit (e.g., 2300 mg for general health or 1500 mg for hypertension) to see how much of your budget this serving uses.
- Click Calculate to see the sodium content in mg and g, and your daily percentage if a limit was entered.
- Use the remaining sodium budget figure to plan the rest of your meals and avoid exceeding your daily target.
Frequently Asked Questions
How much sodium is in a teaspoon of salt?
A level teaspoon of fine table salt weighs approximately 6 grams and contains about 2,360 mg of sodium — more than the 2,300 mg daily limit recommended by US dietary guidelines. A slightly heaped teaspoon can easily exceed 2,500 mg. For coarser salts like kosher or sea salt, the same volume weighs less and therefore contains slightly less sodium.
Is sea salt healthier than table salt?
From a sodium perspective, sea salt and table salt are essentially equivalent. Both contain approximately 38–40% sodium by weight. Sea salt retains trace minerals that are removed during the refining of table salt, but these minerals are present in such small quantities that they provide no meaningful nutritional benefit. The health impact of sea salt versus table salt is determined entirely by how much is consumed.
Does pink Himalayan salt have less sodium?
Pink Himalayan salt contains slightly less sodium by weight than table salt (approximately 36% vs. 39%), but the difference is very small — about 30 mg per gram of salt. Marketing claims that Himalayan salt is a 'lower sodium' option are misleading because in practice it is used in similar amounts to table salt, delivering nearly the same sodium load per serving.
How can I reduce my sodium intake?
The most effective strategy is to reduce consumption of processed and packaged foods, which account for about 70–75% of dietary sodium in Western diets. Reading nutrition labels, choosing low-sodium products, cooking at home with fresh ingredients, and gradually reducing the amount of salt added during cooking can all help. Your taste perception of saltiness adapts over several weeks, making lower-sodium foods taste normal over time.
What is the recommended daily sodium intake?
The World Health Organization recommends less than 2,000 mg of sodium per day for adults. The US Dietary Guidelines set the limit at 2,300 mg, equivalent to about one teaspoon of table salt. The American Heart Association recommends no more than 1,500 mg per day for individuals with high blood pressure or heart disease. Most adults in developed countries currently consume 3,000–4,000 mg per day.
Why do nutrition labels show sodium rather than salt?
Nutrition labels report sodium (not salt) because sodium is the biologically active component responsible for blood pressure effects and fluid balance. Salt contains both sodium and chloride, but only sodium is physiologically relevant in the context of hypertension and cardiovascular risk. Reporting sodium directly avoids confusion, since the same amount of different salts can deliver different sodium quantities depending on their composition.
