A tablespoon of garlic powder is 9 g, approximately. Recipes use tablespoons for small amounts, which is exactly where guessing goes wrong, because being out by half a spoon matters far more in a single tablespoon than in a whole cup. The conversion itself is simple: a cup of garlic powder weighs 144 g, and a tablespoon is one sixteenth of a cup, so 144 ÷ 16 = 9 g.
The figure comes from USDA, measured spooned and levelled, and every result on this page is labelled approximate. Keep the scale nearby for anything that has to be exact.
About Garlic Powder
Dehydrated garlic ground fine; much more concentrated than fresh. Rubs, dressings, roasted vegetables and sauces. That is why it shows up in recipes measured by the tablespoon: it is used in amounts too small for a cup measure to be practical, yet large enough that guessing the weight can throw a dish off. Knowing that one tablespoon weighs 9 g lets you move between the spoon and the scale without stopping to work it out.
Storage. Airtight jar, cool and dry, up to 1 year.
Tablespoon to grams table
| Tablespoons | Grams |
|---|---|
| 1 teaspoon | 3 g |
| 1 tablespoon | 9 g |
| 2 tablespoons | 18 g |
| 3 tablespoons | 27 g |
| 4 tablespoons | 36 g |
| 5 tablespoons | 45 g |
| 6 tablespoons | 54 g |
| 7 tablespoons | 63 g |

| 10 tablespoons | 90 g |
| 11 tablespoons | 99 g |
| 12 tablespoons | 108 g |

| 14 tablespoons | 126 g |
| 15 tablespoons | 135 g |
| 16 tablespoons | 144 g |
One tablespoon is one sixteenth of a cup, so every figure above is the cup weight of 144 g divided by 16 and rounded to one decimal place. Sixteen tablespoons make one cup, which is why the last row of the table matches the cup weight exactly. All figures are approximate; verify with a kitchen scale when it matters.
Cups to grams for reference
Most recipes switch between cups and tablespoons, so here is the same ingredient measured in cups. Use this table when a recipe gives a cup amount and you want to weigh it, or when you have already measured in tablespoons and want to check the total.
| Cups | Tablespoons | Grams |
|---|---|---|
| 1/4 cup | 4 tablespoons | 36 g |
| 1/3 cup | 5 tablespoons plus 1 teaspoon | 48 g |
| 1/2 cup | 8 tablespoons | 72 g |
| 2/3 cup | 10 tablespoons plus 2 teaspoons | 96 g |
| 3/4 cup | 12 tablespoons | 108 g |
| 1 cup | 16 tablespoons | 144 g |
| 1 1/2 cups | 24 tablespoons | 216 g |
| 2 cups | 32 tablespoons | 288 g |
Worked examples
A spice rub for a roast
A spice rub for a whole chicken or a joint of meat uses 2 tablespoons of garlic powder, about 18 g, mixed with salt, oil and other spices. Two tablespoons spread over the surface gives an even coating that flavours the skin without overwhelming the meat. Rub it in at least half an hour before cooking, and pat the surface dry first so the rub sticks instead of sliding off.
A curry for four people
A curry for four people often starts with 1 tablespoon of garlic powder, 9 g, bloomed in hot oil with onion and garlic before the liquid goes in. Blooming the spice in oil wakes up its flavour in a way that adding it to water never does, and one tablespoon is enough to season a whole pot. Cook it for a minute until it smells fragrant, but do not let it catch, because burnt spice turns bitter and there is no fixing it.
A batch of spiced baking
A batch of spiced biscuits or a loaf cake uses 1 tablespoon of garlic powder, 9 g, mixed into the dry ingredients before the wet ones are added. One tablespoon is a strong dose for a single bake, so weigh it rather than guessing, and mix it through the flour first so it is distributed evenly instead of sitting in pockets. The spice should be a background warmth, not the first thing you taste.
How the figure is measured
Garlic Powder is measured spooned and levelled: spoon it loosely into the tablespoon, then sweep the top flat with the back of a knife. Do not scoop directly from the bag or jar, because scooping packs the ingredient down and a scooped spoon can weigh far more than a spooned one. The spoon-and-level method is the one the source data assumes, so it is the method that makes the numbers on this page true.
The cup weight of 144 g comes from USDA. The tablespoon figure is that cup weight divided by 16, rounded to one decimal place, which is why the table is consistent from one row to the next. All results are approximate: brand, grind, humidity and temperature all move the real weight a little, so when a recipe has to work the first time, weigh the ingredient on a kitchen scale and use these numbers as a guide.
Scaling the recipe up and down
Tablespoons scale cleanly once you know the weight of one spoon. A recipe that calls for 8 tablespoons of garlic powder needs 72 g, and doubling it to 16 tablespoons means 144 g, exactly one cup. Halving works the same way: 4 tablespoons is 36 g, and 2 tablespoons is 18 g. The rule that matters is to scale every ingredient by the same factor, because changing one ingredient without changing the others throws the recipe out of balance.
When a recipe gives a weight instead of spoonfuls, work backwards: 100 g of garlic powder is about 11.1 tablespoons, and 50 g is about 5.6 tablespoons. Round to the nearest half tablespoon when you are measuring by hand, and accept that the result will be a gram or two off, which is fine for most cooking. For large amounts, stop counting spoons and switch to a cup measure or a scale: counting out 16 tablespoons is slow and error-prone, and a cup is faster and more accurate.
Frequently asked questions
How many grams is a tablespoon of garlic powder?
One tablespoon of garlic powder weighs 9 g, approximately. The figure comes from dividing the cup weight of 144 g by 16, since one tablespoon is one sixteenth of a cup. One teaspoon is 3 g, and one cup is 144 g.
How many tablespoons of garlic powder are in 100 g?
About 11.1 tablespoons. The calculation is 100 g divided by 9 g per tablespoon, which gives 11.1. In practice, measure 11.1 level tablespoons and accept that the result will be a gram or two off, or weigh the ingredient directly if the recipe needs to be exact.
How many tablespoons of garlic powder are in a cup?
There are 16 tablespoons in one US cup, so one cup of garlic powder is 16 tablespoons and weighs 144 g. Half a cup is 8 tablespoons (72 g), a quarter cup is 4 tablespoons (36 g), and three quarters of a cup is 12 tablespoons (108 g).
Can I use a regular eating spoon instead of a measuring tablespoon?
It is not a good idea. Eating spoons vary widely in size and shape, and a tablespoon from a cutlery drawer can hold noticeably more or less than a standard measuring tablespoon. A set of measuring spoons costs very little and is the only way to make the figures on this page true in your kitchen.
Is 9 g per tablespoon exact or approximate?
It is approximate. The cup weight of 144 g comes from USDA, measured spooned and levelled, and the real weight of a tablespoon varies with brand, grind, humidity and how the spoon is filled. For most cooking the approximation is fine, and for baking or any recipe that has to work the first time, verify with a kitchen scale.
Common mistakes to avoid
- Scooping directly from the bag, which packs the ingredient down and makes a spoonful weigh far more than a spooned one.
- Leaving the spoon heaped instead of levelling it, which adds an unpredictable extra amount every time.
- Measuring a damp or clumped ingredient without breaking it up first, which leaves air pockets and a short measure.
- Using a regular eating spoon instead of a measuring tablespoon, since eating spoons vary widely in size.
The thread running through all of these is the same: a tablespoon is only a standard measure when it is filled in the standard way. Measure garlic powder spooned and levelled, level it off, and check the weight on a scale when the recipe has to be right, and the numbers on this page will serve you well.
