How to use it
- Enter amount, measure, measuring spoons, spice or herb and your own weighed teaspoon in grams (optional).
- The result appears straight away and updates as you edit.
- Copy the result, or copy a link that keeps the same values to share it.
How it is calculated
grams = spoons × weight per spoon for the chosen spice from USDA FoodData Central (SR Legacy). Where USDA lists no tablespoon it is derived by volume as 3 × the teaspoon weight. For metric spoons the weight is multiplied by the volume ratio: 5 ÷ 4.929 for a teaspoon and 15 ÷ 14.787 for a tablespoon, about 1.4% more.
Example
Inputs: Amount = 2, Measure = Teaspoon, Measuring spoons = US spoons (as in the source), Spice or herb = Ground cloves. Result: Weight in grams: 4.2 g; Grams per teaspoon used: 2.1 g.
Limits and caveats
- Figures are for a spoon leveled with a knife; a heaped spoon weighs clearly more.
- Grind, moisture and brand change the weight, so if you weigh your own spoon once, enter it in the optional box.
- Ready blends such as mixed Arabic spice or za'atar with sesame are not listed because their recipes vary.
Questions about this tool
Why do dried herbs weigh much less than ground spices?
Dried leaves are light and leave gaps, so a teaspoon of dried mint is 0.5 g while turmeric is 3 g in USDA data.
Is the thyme in the list the same as za'atar?
No. It is dried thyme leaves only; the za'atar blend with sesame and sumac weighs differently.
Does it change with metric measuring spoons?
Slightly. The figures are for US spoons (4.93 mL and 14.79 mL); metric spoons of 5 mL and 15 mL hold about 1.4% more, so pick "Metric spoons" to adjust.
