Convert level teaspoons to grams for common ingredients, or use your own weighed spoonful for packed and heaping measurements.
Weigh spoonfuls using your selected fill style, then divide by the count. There is no universal packed or heaping multiplier.

How to use our Teaspoons to Grams Converter
- Choose an item in Ingredient, because one teaspoon of sugar, flour, salt, or honey does not weigh the same.
- Enter your amount in Teaspoons (tsp). Decimals such as 0.25, 0.5, and 1.5 work.
- Pick Measurement style. Non-level dry ingredients require Measured grams per teaspoon from your own weighing; no fixed packing multiplier is assumed.
- Click Calculate to see Grams, Grams per teaspoon and Teaspoons in milliliters. No unsupported typical-range interval is displayed.
- Check Grams per teaspoon and Note. Use the recipe weight or weigh ingredients directly when precision matters.
Definitions
Ingredient: The food you are converting. Each ingredient has its own grams-per-teaspoon value.
Measurement style: How full the spoon was, such as level, lightly packed, packed, or heaping.
Grams per teaspoon: How much 1 teaspoon of the chosen ingredient weighs, in grams.
Uncertainty: No validated low-to-high range is available for these ingredient and packing combinations.
Teaspoons in milliliters: The same volume shown in metric units. This calculator uses the US teaspoon.
Density: How much mass fits into a certain space. This is why the same spoonful can weigh differently for different ingredients.
Common mistakes and quick fixes
Mistake: Using the same Teaspoons (tsp) value for every Ingredient and expecting the same Grams .
Fix: Always choose the correct Ingredient first, because teaspoons measure volume and grams measure weight.
Mistake: Leaving Teaspoons (tsp) blank and expecting it to act like zero.
Fix: Enter a real number in Teaspoons (tsp) . If you mean none, type 0.
Mistake: Picking Measurement style as packed or heaping when your spoon was actually level.
Fix: Match Measurement style to how you filled the spoon. For most recipe testing, level is the safest choice.
Mistake: Treating a chart estimate as a guaranteed range. Fix: Weigh the ingredient; no universal error band is calculated.
Mistake: Confusing Teaspoons in milliliters with Grams for thick or dry ingredients.
Fix: Treat Teaspoons in milliliters as volume only. Use Grams for weight.
Mistake: Ignoring the Note when a baking recipe needs precision.
Fix: Read the Note . If accuracy matters, weigh the ingredient directly instead of relying only on spoons.
Limitations & Key Assumptions / Boundary Conditions
- The result is an estimate based on the selected ingredient and spoon-fill style, not a lab measurement.
- This tool only supports the listed ingredients. If your ingredient is different, the conversion may not match.
- For liquids such as water, spoon-fill style does not meaningfully change the calculation, so the tool treats them as level.
- Texture, clumping, moisture, brand, temperature, and how tightly you pack a spoon can change the real weight.
- The calculator uses the US teaspoon, which is 4.92892159375 mL, not the rounded 5 mL food-labeling teaspoon.
- The tool does not assign a confidence interval or a generic variation percentage.
- Negative teaspoon values are not physically meaningful here, so they should be corrected before calculating.
Methodology
How the converter works
Teaspoons are converted to milliliters separately. Grams equal teaspoons multiplied by a level-spoon reference, or by your measured mass per spoonful for a non-level style.
mL = tsp * 4.92892159375
g = tsp * g_per_tsp_style
g_per_tsp_style = level reference OR user-measured grams per spoonful
No assumed lower uncertainty bound.
No assumed upper uncertainty bound.
Ingredient factors and style adjustment
Level references include King Arthur granulated sugar at 198 g per cup (48 teaspoons), flour at 120 g per cup, baking powder at 4 g per teaspoon and baking soda at 3 g per half-teaspoon. These are ingredient approximations, not universal densities.
No fixed packing multipliers are applied. For non-level dry ingredients, use measured grams per spoonful.
Worked mini-example
Suppose you choose All-purpose flour, enter 2 in Teaspoons (tsp), and keep Measurement style at level.
g_per_tsp_style = 120 / 48 = 2.5 g/tsp
g = 2 * 2.5 = 5 g
mL = 2 * 4.92892159375 = 9.8578431875 mL
For 2 level teaspoons of all-purpose flour using 120 g per 48-teaspoon US cup, the result is 5 g and about 9.86 mL.
Assumptions used
The converter uses the US teaspoon and ingredient-specific approximate masses. Packed and heaping dry ingredients use your measured mass; no invented variation range is shown.
