A level teaspoon of garlic powder weighs about 3.1 g, according to USDA FoodData Central. That makes a tablespoon about 9.3 g, and it means the grams in a teaspoon of garlic powder run higher than lighter spices like ground ginger, which USDA puts at 1.8 g per teaspoon.
| Amount | Grams |
|---|---|
| 1/4 tsp | 0.8 g |
| 1/2 tsp | 1.6 g |
| 1 tsp | 3.1 g |
| 1 tbsp | 9.3 g |
| 1/4 cup | 37.2 g |
| 1/2 cup | 74 g |
| 1 cup | 149 g |
Garlic powder vs granulated garlic
These two sit side by side on the shelf and get swapped all the time, but they aren't the same texture. Garlic powder is ground fine, a lot like flour. Granulated garlic is coarser, closer to cornmeal.
That difference matters in a spoon. Fine powder packs tightly, while coarser granules leave small gaps between them. So a teaspoon of one won't necessarily weigh the same as a teaspoon of the other. The USDA figure here is for garlic powder. If you're using granulated garlic, weigh a level teaspoon from your own jar to find its number.
Why the grams in a teaspoon of garlic powder vary
- Moisture. Garlic powder soaks up humidity and can harden into lumps, or even one solid block. Clumpy powder is hard to measure evenly.
- Packing. Pressing the spoon into a full jar squeezes in extra powder.
- Brand. Grind size varies a little from brand to brand.
- Level vs heaped. A heaped spoon can hold a lot more than a level one. Recipes mean level.
To keep it loose, close the lid tightly after each use and avoid shaking the jar right over a steaming pot. If it does clump, break it up with a fork or give it a quick pulse in a spice grinder before measuring.
Garlic powder in everyday cooking
Garlic powder goes into rubs, dressings and seasoning mixes where an even spread matters. Here's what common amounts weigh:
- Garlic bread butter with 1 tsp: about 3.1 g.
- Burger seasoning with 1/2 tsp: about 1.6 g.
- Homemade ranch seasoning with 2 tsp: about 6.2 g.
- A big jar of all purpose rub with 1/4 cup: about 37.2 g.
Once you've got a mix you love, record it in grams. Weighing each spice into the jar next time gives you the same blend without the guesswork.
Easy garlic powder mistakes
- Swapping granulated garlic spoon for spoon. The texture is different, so weigh it instead.
- Confusing garlic powder with garlic salt. Garlic salt has salt mixed in, so it weighs differently per spoon and makes the dish saltier.
- Shaking the jar over a steaming pan. The steam gets inside and starts the clumping.
- Heaping the spoon. A heaped teaspoon of garlic powder can overwhelm a small batch of dressing.
How to measure garlic powder
- Break up any lumps first.
- Zero your scale with the bowl or spoon in place.
- Spoon the powder in loosely and level it if you're going by volume.
- Aim for about 3.1 g per level teaspoon.
A practical shortcut for seasoning mixes: a MeasureMate digital measuring spoon scoops and weighs in one step, so you can measure right from the jar. The display reads in 0.1 g steps, and the tare button zeroes the reading between spices. The spoon head comes off for cleaning, which helps when you move from garlic to something sweet.
Quick questions
How many grams is a tablespoon of garlic powder?
About 9.3 g, which is three level teaspoons at 3.1 g each.
How many teaspoons is 5 g of garlic powder?
About 1 1/2 tsp, plus a little. At 3.1 g per teaspoon, 5 g works out to about 1.6 tsp.
Why did my garlic powder turn hard?
It pulled in moisture from the air. Keep the lid tight and store it away from the stove.
