To convert grams of ground turmeric into teaspoons, multiply by 0.33333333: one gram comes to 0.33333333 teaspoons. Every ingredient has its own figure here, because the units are measuring different things and only the density links them.
Water is the yardstick: 1 mL of it weighs 1 g. Ground turmeric comes in at 0.60865 g per mL, or 60.87% of water, which is why a cup of it is 144 g rather than 236.6 g. Volume and weight only line up for water, and only in metric.
A level teaspoon of ground turmeric weighs 3 g. A kitchen scale that reads to the nearest gram is therefore working at roughly 33.3% resolution on a single spoonful, which is why measuring spoons beat scales below about 5 g and lose to them above it. Three teaspoons make a tablespoon, so the same spoonful is 9 g if the recipe scales up.
Grams are the unit this conversion is really for. A domestic scale resolves to a gram, which is 0.694% of a cup of ground turmeric, so weighing gets an accuracy no measuring cup can reach. A 500 g pack of it is 3.472 cups, and a 1 kg pack 6.944.
The condition this weight assumes: Denser than most ground spices because the rhizome it comes from is mostly starch.
The formula
grams- The amount of ground turmeric you are converting, in grams
0.333333333333- Teaspoons per gram for ground turmeric, from its density of 0.60865 g/mL
teaspoons- The equivalent quantity in teaspoons
How it works, step by step
- Enter the quantity in grams.
- It is multiplied by 0.333333333333, the teaspoons-per-gram figure for ground turmeric.
- The result appears in teaspoons, with a second reading in mL beneath it.
- Use the measure table if you want a standard recipe quantity rather than a number you type in.
Worked examples
50 g of ground turmeric in teaspoons
50 g of ground turmeric weighs out at 16.6667 teaspoons. Divide 16.6667 by 0.33333333 and you get back to 50 g, which is the quickest check that the factor is the right way up.
150 g of ground turmeric in teaspoons
Take 150 g of ground turmeric: 150 × 0.33333333 gives 50 teaspoons. Doubling the batch takes it to 100 teaspoons, because the relationship is a straight proportion once the density is known.
500 g of ground turmeric in teaspoons
Take 500 g of ground turmeric: 500 × 0.33333333 gives 166.667 teaspoons. Doubling the batch takes it to 333.333 teaspoons, because the relationship is a straight proportion once the density is known.

Frequently asked questions
How many teaspoons are in 1 g of ground turmeric?
One gram of ground turmeric is 0.33333333 teaspoons. Half that quantity is 0.166667 teaspoons and double it is 0.666667 teaspoons, so the figure scales straight up and down — there is no offset in this conversion, only the factor.
Why is a cup of ground turmeric not 236 g like water?
Because weight per cup depends on what is in the cup. Ground turmeric has a density of 0.60865 g per mL where water has 1.00, so a cup of it weighs 144 g rather than 236.6 g. That is a difference of 92.6 g per cup, and it is the reason a single volume-to-weight factor cannot be applied to every ingredient.
Does how I measure it change the weight?
Yes, and by more than most people expect. Handling changes the weight of a cup of ground turmeric by roughly 20% — about 14.4 g either side of 144 g — because denser than most ground spices because the rhizome it comes from is mostly starch. Weighing removes the question entirely.
Is a fluid ounce of ground turmeric the same as an ounce?
No. A fluid ounce is a volume — one eighth of a US cup, 29.57 mL — and an ounce is a weight. One fluid ounce of ground turmeric weighs 0.6349 oz, so the two readings differ by 36.5%. They coincide only for something with the density of water, and then only roughly.
Is this a US cup or a metric cup?
US customary: 236.59 mL, which is the cup every US recipe means. A metric cup is 250 mL, so the same cup of ground turmeric would weigh 152.16 g instead of 144 g — 8.16 g more, or 5.67%. Australian and some European recipes use the metric cup, and the difference is large enough to matter in baking.
Do I need a scale for this, or will measuring cups do?
At this size the spoon wins. One teaspoon of ground turmeric is 3 g, and a scale reading to the nearest gram is working at 33.3% resolution on that — a measuring spoon is the more accurate instrument below about 5 g, which is why spice quantities are still written in spoons.
How much does 2 tsp of ground turmeric weigh?
2 tsp of ground turmeric comes to 6 g, or 6 grams. This page runs that calculation in reverse — enter a weight and it returns the volume — and the teaspoons-to-grams page does it in the direction the question is usually asked.
