Grams To Tsp
100 g of sugar is 24 teaspoons, but 100 g of table salt is only 16.4 teaspoons.
Quick answer: Multiply the grams by 48 and divide by the grams per cup. For example, 100 g of granulated sugar is 24 tsp, 100 g of water is 20.288 tsp and 100 g of brown sugar (packed) is 22.535 tsp.
The grams to tsp formula
Teaspoons equal grams times 48, divided by the grams in one cup.
Pick the ingredient first, since each one has its own weight per cup.
Take 100 g of granulated sugar. 100 × 48 ÷ 200 gives 24 tsp.
Take 100 g of water. 100 × 48 ÷ 236.59 gives 20.288 tsp.
Grams and teaspoons
A gram is weight, and a US teaspoon is one 48th of a cup (Wikipedia: Cup (unit)).
A teaspoon holds about 4.2 g of sugar, 6.1 g of salt and 2.6 g of flour.
How to convert grams to tsp step by step
- Enter the amount in grams.
- Pick the ingredient, or enter its grams per cup.
- Read the result in Teaspoons (US tsp).
- Check it against the quick table.
Example 1: 100 g of granulated sugar
- Start with 100 g of granulated sugar.
- 100 × 48 ÷ 200 = 24.
- The amount is 24 tsp.
100 g of granulated sugar = 24 tsp
Example 2: 100 g of water
- Start with 100 g of water.
- 100 × 48 ÷ 236.59 = 20.288.
- The amount is 20.288 tsp.
100 g of water = 20.288 tsp
Example 3: 100 g of brown sugar (packed)
- Start with 100 g of brown sugar (packed).
- 100 × 48 ÷ 213 = 22.535.
- The amount is 22.535 tsp.
100 g of brown sugar (packed) = 22.535 tsp
Round only at the end. Weights per cup are good to about 5 percent, so treat the answer as a cooking guide and not as a lab value.

A quick mental shortcut for grams to tsp
For sugar, divide the grams by 4. For salt, divide by 6.
For flour, divide by 2.6.
Why it is not one number
Some people say 1 tsp is 5 g. That is true for water, but not for most foods.
Check the table for your ingredient before you spoon.
Why the ingredient changes the answer
One US cup of granulated sugar weighs about 200 g, one cup of water weighs about 236.59 g, and one cup of brown sugar (packed) weighs about 213 g.
So 100 g gives 24 tsp for granulated sugar, 20.288 tsp for water and 22.535 tsp for brown sugar (packed).
Going the other way
Take 24 tsp of granulated sugar. Reverse the sum and you get 100 g.
If the round trip does not return your start value, one number was typed or rounded wrongly.
If your ingredient is not listed
Weigh one level US cup of it and use that number as the grams per cup. Chart weights vary by brand and by how the cup is filled.
Flour weights in published charts assume the scoop and level method (Baking Like a Chef: Cups to Grams Conversions).
The same amount for other ingredients
The page above uses granulated sugar as its main ingredient. At the default amount of 100 g, it gives 24 tsp.
At 100 g, water gives 20.3 tsp. At 100 g, brown sugar (packed) gives 22.5 tsp. At 100 g, powdered sugar gives 40 tsp.
At 100 g, all-purpose flour gives 38.4 tsp. At 100 g, bread flour gives 37.8 tsp. At 100 g, butter gives 21.1 tsp.
At 100 g, table salt gives 16.4 tsp. At 100 g, baking soda gives 20.9 tsp. At 100 g, baking powder gives 25 tsp.
At 100 g, cocoa powder gives 56.5 tsp. At 100 g, honey gives 14.1 tsp. At 100 g, milk gives 19.6 tsp.
At 100 g, vegetable oil gives 22 tsp. At 100 g, uncooked white rice gives 25.9 tsp. At 100 g, rolled oats gives 53.3 tsp.
The spread shows why one factor cannot serve every food. Pick your own ingredient from the list before you trust the answer.
Doubling, halving and scaling
For granulated sugar, 50 g is 12 tsp. For granulated sugar, 200 g is 48 tsp. For granulated sugar, 500 g is 120 tsp.
For granulated sugar, 1,000 g is 240 tsp. The answer scales in a straight line, so doubling the input doubles the output.
Checking and rounding the result
To check the answer, run the sum the other way with the same weight per cup. Starting from 24 tsp of granulated sugar you should land back on 100 g.
Rounding the result to three significant digits gives 24 tsp. That is off by about 0.00 percent, which is fine for cooking but worth keeping in mind for large batches.

Where this conversion is used
Cooks use it when a recipe lists grams and the scale is missing.
Bakers and home brewers measure small amounts of spices, yeast or salt.
Common mistakes to avoid
- Using 5 g for every food. Only water comes close.
- Using heaped spoons. Level them.
- Mixing tsp and tbsp. 1 tbsp is 3 tsp.
- Using dry weights for liquids. Pick the right ingredient from the list.
