With this grams-to-teaspoons converter, you'll quickly convert between grams – the basic unit of weight (mass) in the metric system – and teaspoons (tsp), which are a measure of volume often used in cooking.

Wondering how many grams of sugar are in a teaspoon? Want to know how many teaspoons are in a tablespoon? Have baking powder in grams in a pancake recipe, but you prefer teaspoons? We've taken care of everything! Scroll down to read more about grams to tsp conversion or have a quick look at the conversion table for fourteen ingredients that often appear in the teaspoon unit.

How many grams in a teaspoon?

Well, it's impossible to answer without additional information, as it depends on the product density. As you intuitively know, there are differences in the weight of a cocoa powder teaspoon and how many grams of sugar are in a teaspoon. But no worries! This grams-to-teaspoons conversion calculator is here to help you. Experiment with our tool, choose different products or type in their density, and we'll find the weight of the ingredient in grams or volume, measured in teaspoons.

🙋 To refresh the notion of density (which you've undoubtedly learned at school!), visit our density calculator.

If you want to quickly compare how many grams are in a teaspoon of various products, simply have a look at this table:

2.6 g

We've averaged that value because the differences between metric and US tsp are minor when dealing with only one spoon. More inconsistencies are brought by differences in the density of the products coming from various manufacturers. So remember that the table above (and the grams to teaspoons converter itself) is a rough approximation and can be used in everyday life, but not necessarily when high-precision measurements are needed.

How many teaspoons in a tablespoon?

There are 3 teaspoons in a tablespoon. No matter if you're using metric or US measures – if you're sticking to Imperial, there are always three teaspoons in a tablespoon:

  • 1 tsp (5 ml) × 3 = 1 tbsp (15 ml)
  • 1 US tsp (4.93 ml) × 3 = 1 US tbsp (14.79 ml)
One tablespoon is equal to three teaspoons

Be careful, though – staying in the US doesn't exactly mean that you'll find only US teaspoons there. For example, in nutritional labeling and medicine, the teaspoon always has 5 ml, which is simply the metric teaspoon.

How many teaspoons in a cup?

There are 48 teaspoons in one cup. Indeed, there are 16 tablespoons in a cup, and one tablespoon equals exactly three teaspoons. So 1 cup = 16 tbsp = 16 × 3 tsp = 48 tsp.

How many calories in a teaspoon of sugar?

Thanks to the grams to teaspoons converter and table, you've discovered that a spoon of sugar weighs around 4.2 grams. Wondering how many calories are in a teaspoon of sugar? It's estimated that one teaspoon of sugar contains 16 calories, and one tablespoon contains 48 calories.

According to American Heart Association recommendations, we should limit the amount of added sugars to no more than:

  • 100 kcal/day for women (which equals 6 teaspoons / 24 grams)
  • 150 kcal/day for men (which equals 9 teaspoons / 36 grams)

Unfortunately, sugar is added to almost all processed food. Also, we add it ourselves – many people use sugar with, e.g., coffee or tea. Researchers found out that the average US coffee drinker is consuming almost three teaspoons of sugar each day and an average tea lover – 2 spoons per day. However, the biggest source of added sugars for Americans are sodas, energy drinks, and sports drinks:

Have you noticed that one can of almost any type of soda exceeds our daily recommended amount of added sugar? We didn't count other products eaten every day, such as dairy, cereals, fruit drinks, cakes and candies, dairy desserts, etc. Sum all of those, and the amount of added sugars will shoot through the roof – don't wait any longer.

How many grams in a teaspoon of sugar?

There are 4.2 grams in a teaspoon of granulated sugar. For brown sugar, one teaspoon is 4 g; for powdered sugar, one teaspoon is only 2.8 g.

How many grams in 3 teaspoons of olive oil?

3 teaspoons of olive oil is 13.8 grams. To calculate this result, you need to know that 1 teaspoon of olive oil is equivalent to 4.6 g. So multiplying this number by 3, we get 3 tsp × 4.6 g/tsp = 13.8 g.

How do I convert teaspoons to grams?

To determine how many grams of a substance in several teaspoons:

  1. Multiply the number of teaspoons by the number of g/tsp that is specific for your substance. For granulated sugar, it's 4.2 g/tsp; for olive oil, 4.6 g/tsp.
  2. If you don't know this specific number, the rule of thumb is to multiply by 5 g/tsp.
  3. However, powder substances have a lower density, e.g., powder sugar gives 2.8 g/tsp, while cocoa is 2.6 g/tsp. Hence, for powders multiply instead by 3.
