Instant conversions for standard culinary and measurement values.
| Teaspoons (tsp) | Grams (g) | Notes / Equivalents |
|---|---|---|
| 0.25 tsp | 1.23 g | Water baseline (1.0 g/mL) |
| 0.5 tsp | 2.46 g | Half teaspoon |
| 0.75 tsp | 3.7 g | Three-quarter teaspoon |
| 1 tsp | 4.93 g | 1 level US teaspoon |
| 1.5 tsp | 7.39 g | One and a half tsp |
| 2 tsp | 9.86 g | Two teaspoons |
| 3 tsp | 14.79 g | Equals 1 tablespoon |
| 4 tsp | 19.72 g | Four teaspoons |
| 5 tsp | 24.64 g | Five teaspoons |
Conversion between teaspoons and grams 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 (tsp to g):
grams = teaspoons × 4.92892 × density (g/mL)Reverse (g to tsp):
teaspoons = grams / (4.92892 × density)Teaspoons measure volume (space) while grams measure mass (weight). The bridge connecting them is substance density in g/mL.
For pure water at room temperature (density 1.0 g/mL), 1 US teaspoon equals exactly 4.92892 grams.
Because salt has density 1.22 g/mL, 1 tsp equals ~6.0g. Flour has density ~0.53 g/mL, so 1 tsp equals only ~2.6g.
A US teaspoon is 4.92892 mL (~4.93g water), while an international metric teaspoon is exactly 5.0 mL (5.00g water).
For water and liquid ingredients of similar density, 1 US teaspoon equals approximately 4.93 grams (or 5.0 grams for a metric teaspoon). For dry ingredients, grams depend on density (e.g., salt is ~6.0g, sugar is ~4.2g, flour is ~2.6g).
For water, 1/2 US teaspoon is approximately 2.46 grams. For salt, it is ~3.0g, and for sugar, it is ~2.1g.
Because a teaspoon is a measure of volume and a gram is a measure of weight. A teaspoon filled with dense gold weighs far more than a teaspoon filled with fluffy feathers.
For water, 5 grams is almost exactly 1 US teaspoon (1.01 tsp) or exactly 1 metric teaspoon. For flour, 5 grams requires about 1.9 teaspoons.
