How Many Teaspoons in a Gram of Salt | Conversion That Works

For standard table salt, 1 gram equals roughly 0.17 teaspoons — a fraction that matters when you’re scaling a recipe or watching sodium intake.

Grab a kitchen scale and a set of measuring spoons, and the question isn’t whether you can convert grams of salt to teaspoons — it’s which salt you’re holding. Table salt, kosher salt, and flaky sea salt pack differently into a spoon, so the same gram weight produces different volumes. Here is the exact conversion for every common salt type, the formula that works for any brand, and the mistakes that throw your dish off every time.

Why Salt Type Changes the Conversion

The conversion from grams to teaspoons depends entirely on density — how tightly the salt crystals pack into a teaspoon. Table salt’s fine, uniform grains pack densely at about 6 grams per teaspoon. Coarse, flaky salts leave more air between crystals, so one gram occupies more volume.

Here is how the most common salt types compare at the standard US teaspoon size (4.93 mL):

• Table salt (fine): 6.0 g/tsp — 1 gram equals about 0.17 tsp
• Morton kosher salt: 5.0 g/tsp — 1 gram equals 0.20 tsp
• Diamond Crystal kosher salt: 3.0 g/tsp — 1 gram equals 0.33 tsp
• Fine sea salt: 5.0–6.0 g/tsp — 1 gram equals 0.17–0.20 tsp
• Flaky Maldon sea salt: 3.0–4.0 g/tsp — 1 gram equals 0.25–0.33 tsp
• Coarse sea salt: about 2.5 g/tsp — 1 gram equals about 0.40 tsp

Quick Reference: Table Salt Grams to Teaspoons

For standard fine table salt — the one most recipes assume unless stated otherwise — the numbers are clean and easy to remember:

The Formula That Works for Any Salt

If you are using a brand not listed above, the math is simple: teaspoons = grams ÷ density, where density is the grams-per-teaspoon value printed on the nutrition label or listed in the salt’s spec sheet. For table salt, density is 6 g/tsp, so the standard shortcut is:

teaspoons = grams × 0.1667

Multiply your gram weight by 0.1667 (or simply divide by 6) and you have your volume in teaspoons, rounded to a practical cooking measurement. One gram of table salt becomes 0.17 tsp. Ten grams becomes 1.67 tsp. No calculator needed beyond that.

Four Common Mistakes That Ruin the Conversion

1. Using the table-salt rule for kosher salt. This is by far the biggest trap. Diamond Crystal kosher salt is about half as dense as table salt (3 g/tsp vs. 6 g/tsp). Using the 0.17 conversion on a tablespoon of Diamond Crystal would under-salt your dish by nearly half. Always confirm the salt type before you measure.

2. Confusing weight and volume. Salt and sugar do not weigh the same per teaspoon. Salt is about 6 g/tsp; granulated sugar is about 4.2 g/tsp. A recipe that calls for “1 teaspoon salt, 1 teaspoon sugar” by weight is two different gram amounts.

3. Packing the spoon. The standard 6 g/tsp assumes a level, not packed, teaspoon. Scooping with the spoon or pressing the salt into it adds up to 20% more salt by weight. Level it with a straight edge for accuracy.

4. Rounding too aggressively. Rounding 0.1667 to 0.2 is common but adds about 15% more salt per gram — fine for a pot of chili, risky for a delicate pastry or a sodium-restricted diet. Stick to 0.17 for table salt, 0.33 for Diamond Crystal kosher.

For baking or any high-precision cooking, a digital kitchen scale eliminates all these problems. Measure by weight, and salt type, packing, and rounding errors vanish entirely.
