How to Convert Grams to Teaspoons
Converting grams to teaspoons is quick and easy using our calculator, but it requires two vital pieces of information: the weight you want to convert, and the specific ingredient you are using.
Select the Ingredient
Ingredient density matters. Our tool uses documented ingredient reference weights to estimate the volume of your baking staple.
Enter the Weight (g)
Type in the weight from your recipe. The calculator instantly processes the ingredient's density against metric teaspoon volume (5 ml) to give you the result.
Why Grams and Teaspoons Cannot Use One Fixed Conversion
Many beginner bakers look for a single universal multiplier to convert grams to teaspoons, but this does not exist. Here's why:
Grams = Mass (Weight)
Grams measure how heavy an ingredient is. When you use digital scales, you are measuring the pure mass of the food, regardless of how much space it takes up.
Teaspoons = Volume (Space)
Teaspoons measure how much space an ingredient occupies. Because ingredients pack differently, a teaspoon of heavy salt will weigh significantly more than a teaspoon of light, aerated flour.
Common Grams to Teaspoons Conversions
Using the same reference weights as the calculator, this table gives approximate metric teaspoon equivalents for common baking ingredients.
| Ingredient | 5g | 10g | 20g | 25g |
|---|---|---|---|---|
| Plain Flour | 1.97 tsp | 3.94 tsp | 7.89 tsp | 9.86 tsp |
| Caster Sugar | 1.25 tsp | 2.49 tsp | 4.98 tsp | 6.23 tsp |
| Butter | 1.04 tsp | 2.09 tsp | 4.17 tsp | 5.22 tsp |
| Table Salt | 0.82 tsp | 1.64 tsp | 3.29 tsp | 4.11 tsp |
| Active Dry Yeast | 1.58 tsp | 3.17 tsp | 6.34 tsp | 7.92 tsp |
Specific Ingredient Conversions
Grams to Teaspoons for Flour
Our plain and bread flour reference is about 2.5g per metric teaspoon. Other flour types and packing methods differ; select the matching ingredient and prefer the recipe's gram quantities when available.
Grams to Teaspoons for Sugar
Sugar types vary heavily. Granulated sugar is about 4.2g and caster sugar about 4.0g per metric teaspoon, Brown sugar while packed is denser and icing sugar much less so. And never forget to choose a sugar type in your calculator.
Grams to Teaspoons for Butter
Butter weighs about 4.8g per metric teaspoon in our reference. A US teaspoon is a different volume. Use the calculator's metric teaspoon result, or weigh the butter for more repeatable baking.
Converting Grams to Teaspoons for Yeast & Salt
Small amounts of yeast and salt need careful measurement. This tool uses a dried-yeast packet reference and a table-salt reference; other products can differ. Use a precision scale when the amount is too small to measure reliably with a spoon.
Frequently Asked Questions
How many teaspoons are in 1 gram of granulated sugar?▼
Because grams measure weight and teaspoons measure volume, the exact conversion depends on the density of the ingredient. For granulated sugar, 1 gram is approximately 0.24 teaspoons. Conversely, 1 standard metric teaspoon (5ml) of granulated sugar weighs about 4.2 grams.
What is 5 g in teaspoons?▼
This depends on the ingredient reference. For water, 5g is approximately 1 metric teaspoon, assuming 1 g/ml. For lighter ingredients like all-purpose flour, 5g is nearly 2 teaspoons (1.97 tsp). For denser ingredients like salt, 5g is less than 1 teaspoon in our table-salt reference. Select your specific ingredient for an approximate measurement.
How many teaspoons is 10 grams?▼
As a general guide using metric teaspoons: 10g of water is approximately 2 teaspoons, assuming 1 g/ml. 10g of caster sugar is about 2.5 teaspoons. 10g of all-purpose flour is nearly 4 teaspoons (3.9 teaspoons) because flour is much less dense than sugar or water.
20 grams is how many teaspoons?▼
20 grams of butter equals approximately 4.2 teaspoons. 20 grams of plain flour equals nearly 8 teaspoons (7.9 tsp). Salt is much denser, so 20 grams of table salt is about 3.3 teaspoons.
How do you convert flour from grams to teaspoons?▼
All-purpose flour weighs roughly 2.5 grams per metric teaspoon when measured using the standard spoon-and-level method. To manually convert, you can divide your total grams of flour by 2.5 to find the approximate number of teaspoons. Or, simply use our calculator above for instant results.
Is 1 gram always equal to the same number of teaspoons for every ingredient?▼
No. Grams measure weight while teaspoons measure volume. Because different baking ingredients have different densities, 1 gram of a light ingredient like flour takes up noticeably more teaspoons than 1 gram of a dense ingredient like salt or sugar.
How do I convert teaspoons back to grams?▼
Use the swap arrow button on the calculator above to reverse the conversion direction. Enter the number of teaspoons and select your ingredient to immediately see the weight in grams.
