Convert Coffee Teaspoons to Grams
Ground coffee estimates by grind size, using level US measures.
How many grams are in a teaspoon of coffee?
1 tsp of medium-ground coffee is about 1.9 g. The medium-grind range is 1.5–2.3 g.
Approximate conversion
1 tsp → 1.9 g
Range: 1.5–2.3 g for medium-ground coffee
Common conversions
| US teaspoons | Medium-ground estimate | Medium-ground range |
|---|---|---|
| 0.5 tsp | 0.9 g | 0.7–1.1 g |
| 1 tsp | 1.9 g | 1.5–2.3 g |
| 2 tsp | 3.7 g | 3–4.5 g |
| 3 tsp | 5.6 g | 4.4–6.8 g |
| 4 tsp | 7.5 g | 5.9–9.1 g |
| 5 tsp | 9.4 g | 7.4–11.3 g |
| 6 tsp | 11.2 g | 8.9–13.6 g |
Approximate values for level US measures. Grind size, roast, freshness and scooping method change how much coffee fits.
How coffee teaspoons convert to grams
Grams measure mass, while us teaspoons measure volume. To convert them, you need an estimate of the ground coffee’s bulk density. For this direction, multiply the number of level volume measures by the coffee density.
Brewax uses medium-ground coffee as the default. The calculator and table both use the same measurement model; the displayed range reflects the low and high density values for the selected grind. Use a scale when precision matters.
