How the grams to teaspoons converter works
A teaspoon measures volume, not weight. To convert grams to teaspoons you must know how densely that ingredient packs a teaspoon-sized space. Fine table salt packs more than four times as densely as ground cinnamon, so the same gram weight occupies a completely different number of teaspoons. The calculator stores per-ingredient density values and applies the division automatically.
Worked example: scaling a spice rub
Elena is tripling a spice-rub recipe. The original calls for 2.6 g of cinnamon per batch, but she is making three batches at once, giving her 7.8 g. Her teaspoon measure is the easiest tool to hand. Ground cinnamon has a density of 2.6 g per teaspoon.
Grams to teaspoons for common baking ingredients
Baking relies on precise small quantities — a half-teaspoon of baking soda too much can ruin a cake. Use this table to convert gram weights for the ingredients where small errors matter most.
| Grams | Salt | Sugar | Baking powder | Baking soda | Butter | Yeast |
|---|---|---|---|---|---|---|
| 1 g | 0.18 tsp | 0.24 tsp | 0.22 tsp | 0.17 tsp | 0.21 tsp | 0.32 tsp |
| 2 g | 0.35 tsp | 0.48 tsp | 0.43 tsp | 0.33 tsp | 0.42 tsp | 0.65 tsp |
| 3 g | 0.53 tsp | 0.71 tsp | 0.65 tsp | 0.50 tsp | 0.63 tsp | 0.97 tsp |
| 5 g | 0.88 tsp | 1.19 tsp | 1.09 tsp | 0.83 tsp | 1.06 tsp | 1.61 tsp |
| 10 g | 1.75 tsp | 2.38 tsp | 2.17 tsp | 1.67 tsp | 2.11 tsp | 3.23 tsp |

Tips for accurate teaspoon measurement
Teaspoons are the smallest standard measure in a recipe, which means errors have an outsized effect on flavour and leavening. A few habits make volume measurement almost as reliable as weighing.
- Always level dry ingredients — dip the teaspoon into the jar, mound the ingredient slightly, then sweep a straight knife or offset spatula across the rim. A heaped teaspoon of baking powder can be 20–30% more than a level one — enough to over-leaven and collapse a cake.
- Never shake the spoon to settle — tapping or shaking compacts the ingredient and effectively packs it, raising the gram weight beyond the level-teaspoon density used in this table.
- Salt type is critical — table salt (5.7 g/tsp), Diamond Crystal kosher (2.8 g/tsp), and Morton kosher (4.8 g/tsp) are not interchangeable teaspoon for teaspoon. Always identify which salt the recipe intends before converting.
- Yeast packets are pre-weighed, not pre-measured — a standard US yeast packet contains 7 g (about 2¼ tsp of instant yeast). Use the weight when halving or scaling to avoid buying a packet for a fraction of a teaspoon.
- Vanilla extract pours more easily than it measures — use a dropper or measure into a spoon over a bowl rather than over the batter. Vanilla's density (4.2 g/tsp) is close to water, so the gram-to-teaspoon conversion is nearly 1:1 with water tables.
Accuracy and limitations
Density values for dry ingredients are averages from controlled measurements; actual density in your kitchen can vary by ±10–15% depending on humidity, how the ingredient was stored, and how finely it was ground. Baking soda is notably hygroscopic — it absorbs moisture from the air and can clump, raising its effective density per teaspoon. Sift or stir before measuring to get a consistent result.
For leavening agents — baking powder, baking soda, yeast — the quantity matters chemically, not just for flavour. A 10% error in a teaspoon measure can change the rise meaningfully. When precision is important, use a digital scale set to 0.1 g resolution rather than a teaspoon. This converter is best used for quick scaling checks, ingredient substitution estimates, and situations where a scale is unavailable.
