Convert grams to teaspoons instantly
Because different ingredients have different densities, this calculator lets you choose an ingredient or enter a custom density.
Quick reference
| Grams | Teaspoons | Tablespoons |

If you have ever wondered, “How many teaspoons is 30 grams?” you are asking a smart kitchen question. Grams measure weight, while teaspoons measure volume. To convert correctly, you need the ingredient’s density.
Why grams and teaspoons are not a fixed conversion
There is no single universal answer for grams to teaspoons across all foods. One teaspoon of flour weighs much less than one teaspoon of honey. That is why a high-quality conversion always includes the ingredient.
- Light ingredients (like flour) use fewer grams per teaspoon.
- Dense ingredients (like honey or salt) use more grams per teaspoon.
- Humidity, packing, and brand differences can slightly change results.

Conversion formula
teaspoons = grams ÷ grams per teaspoon
Example: for granulated sugar (about 4.2 g per teaspoon), 21 grams is 21 ÷ 4.2 = 5 teaspoons.
Common ingredient reference values
| Ingredient | Approx. grams per teaspoon | Notes |
|---|---|---|
| Water | 5.0 | Baseline for many liquid comparisons |
| Granulated sugar | 4.2 | Common for baking recipes |
| All-purpose flour | 2.6 | Scoop and level style affects weight |
| Table salt | 6.0 | Fine crystals increase density |
| Honey | 7.1 | Heavier than water |
Tips for better kitchen accuracy
1) Use a digital scale whenever possible
For baking, weight is usually more repeatable than volume. A scale helps you avoid over-packing dry ingredients and improves consistency.
2) Watch ingredient condition
Brown sugar can be loosely packed or tightly packed. Flour can be sifted or compacted. These conditions affect grams-per-teaspoon values.
3) Keep recipe unit systems consistent
Use US teaspoons with US recipes. Mixing metric spoons and US spoons can introduce small errors over multiple ingredients.
