If you are following a recipe and it gives measurements in grams, you may wonder, how many grams is 1 teaspoon of sugar? The quick answer is simple: 1 teaspoon of granulated sugar is about 4 grams.

This is a handy conversion to know when baking, cooking, counting sugar, or changing a recipe from teaspoons to grams. But there is a little more to it. The exact weight can vary depending on the type of sugar and how you fill the teaspoon. In this guide, we will cover everything you need to know about teaspoons to grams of sugar, including common conversions, calories, different types of sugar, and how to measure sugar correctly.

Quick Answer: 1 Teaspoon of Sugar in Grams

For regular white granulated sugar:
1 level teaspoon of sugar ≈ 4 grams
Here is a quick look at some common measurements:
| Teaspoons of Sugar | Approximate Grams |
|---|---|
| 1 teaspoon | 4 grams |
| 2 teaspoons | 8 grams |
| 3 teaspoons | 12 grams |
| 4 teaspoons | 16 grams |
| 5 teaspoons | 20 grams |
| 6 teaspoons | 24 grams |
| 7 teaspoons | 28 grams |
| 8 teaspoons | 32 grams |
| 10 teaspoons | 40 grams |
| 12 teaspoons | 48 grams |
So, if you need a quick conversion, you can use this simple rule:
Teaspoons of sugar × 4 = approximate grams
For example, 6 teaspoons of sugar would be about 24 grams.
Why Is 1 Teaspoon of Sugar About 4 Grams?
A teaspoon and a gram measure two different things.
A teaspoon measures volume, while a gram measures weight.
When you fill a level teaspoon with regular granulated sugar, the amount of sugar usually weighs around 4 grams.
However, it does not mean that every teaspoon of every type of sugar will always weigh exactly 4 grams.
The weight can change depending on:
- The type of sugar
- The size of the sugar crystals
- Whether the sugar is loose or packed
- Whether the teaspoon is level or heaped
That is why we use about 4 grams rather than saying exactly 4 grams.
How Many Grams Are in 1 Tablespoon of Sugar?
If you do not have a teaspoon handy, you can also use a tablespoon.
There are 3 teaspoons in 1 tablespoon.
So:
3 teaspoons × 4 grams = about 12 grams
That means:
1 tablespoon of granulated sugar ≈ 12 grams
Here are a few more useful conversions:
- 1 teaspoon = about 4 grams
- 2 teaspoons = about 8 grams
- 3 teaspoons = about 12 grams
- 1 tablespoon = about 12 grams
- 2 tablespoons = about 24 grams
- 4 tablespoons = about 48 grams
These numbers are approximate and are mainly for regular granulated sugar.
How Many Calories Are in 1 Teaspoon of Sugar?
If you are keeping track of calories, you may also want to know how many calories are in a teaspoon of sugar.
One gram of sugar provides about 4 calories.
Since 1 teaspoon contains approximately 4 grams:
4 grams × 4 calories = about 16 calories
So, 1 teaspoon of sugar has roughly 16 calories.
Keep in mind that this is an estimate. A heaped teaspoon will contain more sugar and therefore more calories.
How Much Sugar Is in 1 Teaspoon?
One teaspoon of regular granulated sugar contains approximately 4 grams of sugar.
This can make it easier to understand sugar amounts listed on food labels.
For example, if a food contains 20 grams of sugar, that is roughly equal to:
20 ÷ 4 = 5 teaspoons of sugar
So, 20 grams of sugar is about 5 teaspoons.
This is only a simple way to visualize the amount. Food labels may include different types of sugar, and not all sugar measurements come from granulated table sugar.
Does 1 Teaspoon of Brown Sugar Equal 4 Grams?
Not always.
Brown sugar is different from regular white sugar because it contains molasses and is often measured by packing it into the measuring cup or spoon.
If a recipe says 1 teaspoon of packed brown sugar, the amount may weigh differently from 1 teaspoon of loose white granulated sugar.
For this reason, you should not automatically use the 4-gram rule for every type of sugar.
If a recipe gives you a weight in grams, using a kitchen scale is the best way to get the right amount.
What About Powdered Sugar?
Powdered sugar, also called confectioners' sugar or icing sugar, is much finer and lighter than granulated sugar.
Because of its fine texture, 1 teaspoon of powdered sugar does not necessarily weigh 4 grams.
The same is true for other types of sugar, such as:
- Brown sugar
- Raw sugar
- Turbinado sugar
- Coconut sugar
- Demerara sugar
- Powdered sugar
Each type can have a different weight per teaspoon.
So when converting sugar from teaspoons to grams, it is important to know which type of sugar you are using.
What Is a Level Teaspoon?
When someone says 1 teaspoon of sugar, they usually mean a level teaspoon unless the recipe says otherwise.
A level teaspoon looks like this:
- Fill the measuring spoon with sugar.
- Let the sugar sit naturally in the spoon.
- Use the straight edge of a knife to gently level off the top.
- You now have a level teaspoon.
A heaped teaspoon contains more sugar because the sugar rises above the top of the spoon.
That small difference can matter when you are baking or trying to measure sugar accurately.
How to Measure Sugar in Grams
If you want the most accurate measurement, a kitchen scale is the easiest option.
Place a bowl on the scale and set the scale to zero. Then add your sugar until the display reaches the number of grams you need.
For example, if your recipe calls for 20 grams of granulated sugar, simply weigh out 20 grams.
This is more accurate than trying to measure five teaspoons, especially when baking.
Teaspoons vs. Grams: Which Is Better?
Both measurements are useful, but they are helpful for different reasons.
Teaspoons
Teaspoons are:
- Easy to use
- Convenient for small amounts
- Common in everyday recipes
- Useful when you do not have a kitchen scale
Grams
Grams are:
- More precise
- Better for baking
- Useful when following recipes from other countries
- Helpful when you need to measure ingredients accurately
If you are making a simple cup of coffee or tea, using a teaspoon is perfectly convenient.
If you are making a cake and the recipe calls for an exact amount of sugar, measuring in grams with a kitchen scale can give you more consistent results.
How to Convert Teaspoons of Sugar to Grams
You do not need a complicated formula.
For regular granulated sugar, simply multiply the number of teaspoons by 4.
Formula:
Number of teaspoons × 4 = approximate grams
Here are a few examples:
4 teaspoons:
4 × 4 = 16 grams
8 teaspoons:
8 × 4 = 32 grams
10 teaspoons:
10 × 4 = 40 grams
15 teaspoons:
15 × 4 = 60 grams
Remember that these are estimates for regular granulated sugar.
How to Convert Grams of Sugar to Teaspoons
You can also go in the opposite direction.
To get an approximate number of teaspoons, divide the grams by 4.
Formula:
Grams ÷ 4 = approximate teaspoons
For example:
12 grams ÷ 4 = 3 teaspoons
So, 12 grams of granulated sugar is approximately 3 teaspoons.
Another example:
40 grams ÷ 4 = 10 teaspoons
So, 40 grams is approximately 10 teaspoons.
Common Sugar Conversions
Here is a quick reference you can save for later:
| Sugar | Approximate Amount |
| 1 teaspoon | 4 grams |
| 2 teaspoons | 8 grams |
| 3 teaspoons | 12 grams |
| 1 tablespoon | 12 grams |
| 4 teaspoons | 16 grams |
| 5 teaspoons | 20 grams |
| 6 teaspoons | 24 grams |
| 10 teaspoons | 40 grams |
| 12 teaspoons | 48 grams |
| ¼ cup | 48 grams |
| ½ cup | 96 grams |
| 1 cup | 192 grams |
The cup measurements above are also approximate and are based on regular granulated sugar.
