How Many Grams in a Teaspoon?
The number of grams in a teaspoon depends entirely on the ingredient's density. Different ingredients have different weights per teaspoon because they have different densities. For example, a teaspoon of salt (6 grams) weighs more than a teaspoon of cocoa powder (2.6 grams) because salt is denser.
Common Ingredient Densities
| Ingredient | Type | Grams per Teaspoon |
|---|---|---|
| Water | — | 5 g |
| Salt | — | 6 g |
| Sugar | Granulated | 4.2 g |
| Powder | 2.8 g | |
| Brown | 4 g | |
| Instant dry yeast | — | 3 g |
| Baking powder | — | 4 g |
| Gelatin | — | 3.6 g |
| Butter | — | 4.6 g |
| Oil | Cooking/Vegetable | 4.4 g |
| Olive | 4.6 g | |
| Sunflower | 4.8 g | |
| Cacao | — | 2.6 g |
Note: These values are approximations. Actual weights may vary slightly based on how ingredients are packed and their specific brand or variety.
These density differences explain why volume measurements (teaspoons, tablespoons, cups) can be inaccurate for baking. Professional bakers prefer weight measurements (grams) because they're more precise and consistent. However, when you need to convert between the two, our calculator handles the density calculations automatically.
How Many Teaspoons in a Tablespoon?
There are 3 teaspoons in a tablespoon. This ratio is consistent across both metric and US measurement systems:
1 tsp (5 ml) × 3 = 1 tbsp (15 ml)1 US tsp (4.93 ml) × 3 = 1 US tbsp (14.79 ml)
This 3:1 ratio is one of the most useful conversions in cooking and baking. It means you can easily scale recipes up or down, and it's why many measuring spoon sets include both teaspoons and tablespoons.
How Many Teaspoons in a Cup?
There are 48 teaspoons in one cup. This is calculated as:
1 cup = 16 tablespoons = 16 × 3 teaspoons = 48 teaspoons
This conversion is particularly useful when scaling recipes. For example, if a recipe calls for 1/4 cup of an ingredient, that's 12 teaspoons. If you need to double the recipe, 1/2 cup equals 24 teaspoons.
How Many Calories in a Teaspoon of Sugar?
One teaspoon of granulated sugar (approximately 4.2 grams) contains about 16 calories. One tablespoon contains 48 calories (3 teaspoons × 16 calories).
Recommended Daily Sugar Intake
According to the American Heart Association, we should limit added sugars to:
- Women: No more than 100 calories/day (6 teaspoons or 24 grams)
- Men: No more than 150 calories/day (9 teaspoons or 36 grams)
Many processed foods and beverages contain significant amounts of added sugar. A single 12-ounce can of soda can contain 9-11 teaspoons of sugar, which exceeds the daily recommended limit. Being aware of sugar content helps make healthier dietary choices.
Conversion Examples
Given: 10 grams of granulated sugar
Density: 4.2 g/tsp
Calculation: 10 ÷ 4.2 = 2.38 teaspoons
Result: 10 grams = 2.38 teaspoons
Given: 3 teaspoons of salt
Density: 6 g/tsp
Calculation: 3 × 6 = 18 grams
Result: 3 teaspoons = 18 grams
Given: 2 tablespoons of butter
Density: 13.8 g/tbsp (or 4.6 g/tsp)
Calculation: 2 × 13.8 = 27.6 grams
Result: 2 tablespoons = 27.6 grams
Given: 5 grams of cocoa powder
Density: 2.6 g/tsp
Calculation: 5 ÷ 2.6 = 1.92 teaspoons
Result: 5 grams = 1.92 teaspoons
