How Many Grams in a Teaspoon of Sugar?

Divide by 4 and you can see it

Twelve grams is hard to picture. A tablespoon isn't. Divide the grams on a nutrition label by 4 and you get teaspoons, so 12 grams is 3 teaspoons, which is a tablespoon, which is something you can see standing in an aisle. The exact figure is 2.91 teaspoons, but I'd stick with the 4, since the mental math is painless and the answer comes out only about 3 percent high.

The number comes from a simple division. The King Arthur Baking chart weighs a cup of granulated sugar at 198 grams, and a cup holds 48 teaspoons, so one teaspoon is 4.125 grams. The calculator rounds that to 4.1, and for a label 4 is plenty. All three describe the same spoonful. To skip the division, switch "From" to grams above, type the label's number and read the teaspoons on the "Same amount" line.

Read the serving before you do the math

That 12 grams belongs to whichever serving is printed on the label, so check what the serving is before you picture anything. If you'd eat the whole package and it holds 2½ servings, multiply first: 30 grams, about 7¼ teaspoons, or 2 tablespoons plus 1¼ teaspoons.

A teaspoon count is a way of visualizing an amount, and that's all I'm using it for here. It tells you nothing about which sugars the food contains or what you ought to do about them. This page stops at the arithmetic.

Is 4 grams of sugar a teaspoon?

Close enough for picturing a label: 4 grams is 0.97 of a teaspoon of granulated sugar. For a recipe, I wouldn't lean on the shortcut across a large amount. Fifty grams by the divide-by-4 method is 12½ teaspoons when the true figure is about 12.1, which is ¼ cup almost exactly, so a cup measure is a better route than counting spoons.

Granulated, brown and confectioners', spoon for spoon

A teaspoon is a fixed volume, so the grams it holds follow the sugar. From the same chart: packed brown sugar comes to about 4.4 grams per teaspoon, and confectioners' sugar to about 2.4, because it's so much lighter in the spoon. Honey is 7 grams and maple syrup 6.5. Change the ingredient in the conversion calculator and the same spoon is re-weighed for you.

Run a 12-gram label through each and the picture changes: 2.9 teaspoons of granulated, 2.7 of packed brown, about 5.1 of confectioners'. I think granulated is the sensible one to imagine, partly because it's the sugar most of us can already see in a spoon, and partly because the divide-by-4 shortcut only holds for it. If you actually need to swap one of these for brown sugar in a recipe, the brown sugar guide deals with what the swap does beyond the weight.

And for a tablespoon or a cup?

A tablespoon of granulated sugar is about 12.4 grams, since it's 3 teaspoons, and a cup is 198 grams. That's also the quick path for a recipe given in grams: 100 grams is very close to ½ cup, which is 99 grams, while reaching it by the teaspoon would take more than 24 of them. For a whole recipe's worth, the cups to grams converter is the better tool.
