Tablespoons of ground turmeric to grams runs on one number, 9 grams per tablespoon. It is a measured property of this ingredient rather than a defined conversion, which is why a generic volume-to-weight tool cannot give you it.
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 tablespoon of ground turmeric is 9 g, which puts a teaspoon at 3 g and a tablespoon and a half — the quantity recipes are fondest of — at 13.5 g. Levelling twice is where the error comes from, so the scale is the faster instrument once the quantity passes a couple of spoons.
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.
How the figure is arrived at: Denser than most ground spices because the rhizome it comes from is mostly starch.
The formula
tablespoons- The amount of ground turmeric you are converting, in tablespoons
9- Grams per tablespoon for ground turmeric, from its density of 0.60865 g/mL
grams- The equivalent quantity in grams
How it works, step by step
- Enter the quantity in tablespoons.
- It is multiplied by 9, the grams-per-tablespoon figure for ground turmeric.
- The result appears in grams, with a second reading in oz beneath it.
- Use the measure table if you want a standard recipe quantity rather than a number you type in.
Worked examples
2 tbsp of ground turmeric in grams
2 tbsp of ground turmeric weighs out at 18 grams. Divide 18 by 9 and you get back to 2 tbsp, which is the quickest check that the factor is the right way up.
4 tbsp of ground turmeric in grams
4 tbsp of ground turmeric weighs out at 36 grams. Divide 36 by 9 and you get back to 4 tbsp, which is the quickest check that the factor is the right way up.
12 tbsp of ground turmeric in grams
12 tbsp of ground turmeric weighs out at 108 grams. Divide 108 by 9 and you get back to 12 tbsp, which is the quickest check that the factor is the right way up.

Frequently asked questions
How many grams are in 1 tbsp of ground turmeric?
One tablespoon of ground turmeric is 9 grams. Half that quantity is 4.5 grams and double it is 18 grams, 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?
A scale, if the result matters. Volume measuring carries a spread of about 20% for ground turmeric — roughly 28.8 g on a 144 g cup — while a domestic scale is accurate to a gram or two. For anything where the ratio of ingredients drives the outcome, bread and pastry above all, weigh it.
How many tablespoons of ground turmeric is 500 g?
500 g of ground turmeric is 55.556 tablespoons — 0.111111 tablespoons to one gram, so 500 × 0.111111 = 55.556. Going that way is a division by 9, or a multiplication by 0.111111 if you prefer.
