Convert grams to teaspoons (g to tsp) with substance density presets. Instantly convert grams of water, salt, sugar, flour, or oil to teaspoons.
teaspoons = grams / (4.92892 × density)Density used: 1 g/mL
Instant conversions for standard culinary and measurement values.
| Grams (g) | Teaspoons (tsp) | Notes / Equivalents |
|---|---|---|
| 1 g | 0.203 tsp | ~1/5 tsp (water baseline) |
| 2 g | 0.406 tsp | ~2/5 tsp |
| 3 g | 0.609 tsp | ~3/5 tsp |
| 4 g | 0.812 tsp | ~4/5 tsp |
| 5 g | 1.014 tsp | ≈ 1 level US teaspoon |
| 10 g | 2.029 tsp | ≈ 2 teaspoons |
| 15 g | 3.043 tsp | ≈ 3 teaspoons (= 1 tbsp) |
| 20 g | 4.058 tsp | ≈ 4 teaspoons |
| 25 g | 5.072 tsp | ≈ 5 teaspoons |
| 50 g | 10.144 tsp | ≈ 10 teaspoons |
Conversion between grams and teaspoons is governed by precise mathematical and physical standards.
Because one unit measures volume and the other measures mass, the conversion depends on substance density. For water (density 1.000 g/mL), 1 US teaspoon equals exactly 4.92892 grams.
Direct (g to tsp):
teaspoons = grams / (4.92892 × density)Reverse (tsp to g):
grams = teaspoons × 4.92892 × densityFor water and liquid ingredients with a density of 1.0 g/mL, 5 grams is almost exactly 1 level US teaspoon (1.01 tsp) or exactly 1 metric teaspoon.
5 grams of table salt requires only ~0.83 teaspoons, whereas 5 grams of light flour requires nearly 1.9 teaspoons.
Nutrition labels in the US list sugar and sodium in grams and milligrams. Converting to teaspoons helps visualize physical food portions.
1 metric teaspoon is defined as exactly 5 mL, which holds exactly 5.00 grams of pure water at 4°C.
For water, 5 grams is approximately 1 level US teaspoon (or exactly 1 metric teaspoon). For sugar, 5g is ~1.2 tsp. For salt, 5g is ~0.83 tsp. For flour, 5g is ~1.9 tsp.
For water, 1 gram equals approximately 0.203 US teaspoons (roughly 1/5 of a teaspoon).
For water, 10 grams equals approximately 2.03 teaspoons. For granulated sugar, 10g is about 2.4 teaspoons.
15 grams of water is approximately 3.04 teaspoons (or 1 tablespoon). 15 grams of table salt is about 2.5 teaspoons.
Because grams measure mass and teaspoons measure volume. A heavy ingredient like honey takes up less volume than a light ingredient like cocoa powder for the exact same gram weight.
