What is a Gram?
A gram (symbol: g) is a unit of mass in the metric system. It equals one-thousandth of a kilogram, making it ideal for measuring small quantities in cooking, baking, and science.
Grams measure weight, not volume. This means 10 grams of flour and 10 grams of sugar weigh the same, but they take up different amounts of space because they have different densities.
What is a Teaspoon?
A teaspoon (symbol: tsp) is a unit of volume used primarily in cooking and medicine. In the United States, one teaspoon equals exactly 4.92892 milliliters.
Teaspoons measure space, not weight. This means one teaspoon of honey weighs more than one teaspoon of flour because honey is denser. This difference is why you need to know the ingredient's density to convert between grams and teaspoons.
How many grams is 1 Teaspoon?
One teaspoon equals different amounts of grams depending on the ingredient. For water, 1 teaspoon equals 4.929 grams. For flour, 1 teaspoon equals 2.6 grams. For sugar, 1 teaspoon equals 4.2 grams.
The exact weight depends on the ingredient's density. Denser ingredients like salt weigh more per teaspoon, while lighter ingredients like flour weigh less.
How many teaspoons are in a gram?
One gram equals different amounts of teaspoons depending on the ingredient. For water, 1 gram equals 0.203 teaspoons. For flour, 1 gram equals 0.385 teaspoons. For sugar, 1 gram equals 0.238 teaspoons.
The conversion varies because grams measure weight while teaspoons measure volume. You must know the ingredient's density to convert accurately.
Why can't I convert grams to teaspoons directly?
Grams measure mass (weight), while teaspoons measure volume (space). These are two different physical properties, so you cannot convert between them without knowing the ingredient's density.
For example, 100 grams of flour takes up more space than 100 grams of sugar because flour is less dense. This means 100 grams of flour equals more teaspoons than 100 grams of sugar.
Density tells you how much mass fits into a given volume. Water has a density of 1 gram per milliliter, making it the baseline for conversions. Other ingredients have different densities, which is why the conversion factor changes for each ingredient.
How do I convert grams to teaspoons?
To convert grams to teaspoons, divide the weight in grams by the ingredient's grams-per-teaspoon value. The formula is:
For example, to convert 50 grams of sugar to teaspoons: 50 ÷ 4.2 = 11.9 teaspoons.
Follow these steps:
- Identify your ingredient
- Find its density in grams per teaspoon (use our table below)
- Divide your gram amount by that density
- The result is your teaspoon amount
How many teaspoons is 10g of water?
10 grams of water equals 2.03 teaspoons. Water has a density of 4.929 grams per teaspoon, so 10 ÷ 4.929 = 2.03 teaspoons.
Water is the baseline for density conversions because its density is exactly 1 gram per milliliter at standard temperature and pressure.
Grams to teaspoons conversion table
Water serves as the reference point for all density conversions. Because pure water has a density of exactly 1 g/ml, it provides the most predictable gram-to-teaspoon ratio. Use this table when converting water-based liquids like broth, tea, or diluted juices.

How many teaspoons in 15g of milk?
15 grams of milk equals 2.95 teaspoons. Milk has a density of 5.097 grams per teaspoon, so 15 ÷ 5.097 = 2.95 teaspoons.
Milk is slightly denser than water because it contains fats, proteins, and sugars dissolved in the liquid.
Milk grams to teaspoons reference
Milk's density varies slightly depending on fat content. Whole milk (3.25% fat) is denser than skim milk because fat molecules are heavier than water. For most cooking purposes, the difference is negligible, but precision bakers may want to account for it.

How many teaspoons is 10g of sugar?
10 grams of granulated sugar equals 2.38 teaspoons. Sugar has a density of 4.2 grams per teaspoon, so 10 ÷ 4.2 = 2.38 teaspoons.
Sugar is slightly less dense than water, which is why 10 grams of sugar takes up a bit more space than 10 grams of water.
Sugar grams to teaspoons chart
Sugar type affects density. Granulated sugar is the standard reference, but brown sugar (packed) is denser at 4.0 g/tsp, while powdered sugar is lighter at 3.0 g/tsp due to added cornstarch. Use the appropriate density for your specific sugar type.

Teaspoons in 5g of salt
5 grams of table salt equals 0.83 teaspoons. Salt has a density of 6 grams per teaspoon, so 5 ÷ 6 = 0.83 teaspoons.
Salt is denser than water, which is why 5 grams of salt takes up less space than 5 grams of water.
Salt conversion reference
Salt type dramatically affects density. Table salt (fine grain) is the densest at 6.0 g/tsp, while kosher salt is much lighter at 4.5 g/tsp due to larger, flakier crystals. Sea salt falls in between. Always check your salt type before converting.

How many teaspoons is 5g of baking powder?
5 grams of baking powder equals 1.09 teaspoons. Baking powder has a density of 4.6 grams per teaspoon, so 5 ÷ 4.6 = 1.09 teaspoons.
Baking powder is slightly less dense than water, which is why 5 grams takes up a bit more space than 5 grams of water.
Baking powder grams to teaspoons reference
Precision matters when measuring baking powder because it's a chemical leavening agent. Too much can cause bitter taste and collapsed baked goods, while too little results in dense, flat products. For small amounts under 5 grams, use a scale rather than volume measurements.

How do I measure ingredients accurately?
For the most accurate results, use a kitchen scale to measure ingredients in grams. Volume measurements like teaspoons can vary based on how you fill the spoon.
If you must use teaspoons, use the spoon-and-level method: spoon the ingredient into the teaspoon until it's heaping, then level it off with a straight edge. Don't pack ingredients unless the recipe specifically says to (like brown sugar).
For flour, sift it before measuring if the recipe calls for sifted flour. Unsifted flour is denser and will give you more flour per teaspoon.
Other Grams to Teaspoons Questions
Does temperature affect the conversion?
Yes, temperature affects density. Most ingredients expand when heated and contract when cooled, changing their density slightly. For everyday cooking, this difference is negligible. For precise scientific work, use temperature-corrected density values.
Why does flour have a different conversion than sugar?
Flour and sugar have different densities. Flour is less dense (2.6 g/tsp) because it contains air pockets between particles. Sugar is denser (4.2 g/tsp) because the crystals pack more tightly. This means the same weight of flour takes up more space than the same weight of sugar.
How accurate is this conversion for baking?
This conversion is accurate for most home baking. Professional bakers use scales for precision, but teaspoon measurements work well for small amounts like baking powder, salt, and spices. For larger amounts of flour or sugar, a scale gives more consistent results.
Can I convert grams to tablespoons or cups?
Yes, use the same density-based approach. One tablespoon equals 3 teaspoons, and one cup equals 48 teaspoons. Divide your grams by the ingredient's grams-per-tablespoon or grams-per-cup value.
What if my ingredient isn't listed?
Find your ingredient's density online or on the packaging. Once you know the grams per teaspoon, divide your weight by that number to get teaspoons. Our density chart includes 30+ common ingredients.
Is this conversion suitable for liquids?
Yes, this converter works for both liquids and dry ingredients. The key is knowing the ingredient's density. Water, milk, oil, and honey all have different densities, so the conversion changes for each.
