Teaspoons to Grams Converter

Enter the number of teaspoons and select your cooking ingredient — the converter instantly calculates the equivalent weight in grams. Because teaspoons measure volume and grams measure mass, the result depends on ingredient density. Choose from common ingredients like water, sugar, salt, flour, and butter, or enter a custom density to convert any spice or seasoning.

Frequently Asked Questions

How many grams are in 1 teaspoon?

It depends on the ingredient. 1 teaspoon of water weighs approximately 5 grams. 1 teaspoon of granulated sugar weighs about 4.2 grams, while 1 teaspoon of salt weighs about 6 grams. The difference comes down to each ingredient's density — denser ingredients weigh more per teaspoon.

Why do teaspoons and grams convert differently for each ingredient?

Teaspoons are a unit of volume, while grams are a unit of mass (weight). To convert between them you need the ingredient's density — how much mass is packed into a given volume. A teaspoon of a dense substance like salt weighs much more than a teaspoon of a light powder like flour.

How many grams of sugar are in 1 teaspoon?

One level teaspoon of granulated sugar weighs approximately 4.2 grams. Powdered (icing) sugar is lighter at around 2.5–3 grams per teaspoon, while packed brown sugar is closer to 4.5–5 grams per teaspoon due to its higher moisture content and density.

How many grams of salt are in 1 teaspoon?

One level teaspoon of table salt weighs approximately 6 grams. Salt is denser than most other common cooking ingredients, which is why it weighs more per teaspoon than sugar or flour.

What is a teaspoon in milliliters (mL)?

A US teaspoon equals exactly 4.92892 mL. A metric teaspoon (used in Australia and some other countries) equals 5 mL. For most cooking purposes the difference is negligible, but this converter uses the US teaspoon standard of ~4.929 mL.

How do I convert teaspoons to grams for a custom ingredient?

Use the formula: grams = teaspoons × 4.9289 × density (g/mL). First look up the density of your ingredient, then multiply by the number of teaspoons and by 4.9289 (the mL volume of one US teaspoon). The 'Custom' option in this converter lets you enter any density directly.

How many grams of flour are in 1 teaspoon?

One teaspoon of all-purpose flour weighs approximately 2.6 grams. Flour is quite light compared to liquids and salts, so the gram value per teaspoon is lower. Always use level teaspoons for accuracy — scooping and packing flour can significantly change the weight.

Why should I measure ingredients in grams instead of teaspoons?

Grams give you a precise, repeatable measurement because they measure mass directly. Teaspoon measurements can vary based on how tightly an ingredient is packed, its moisture level, and even the size of the spoon. For baking especially, weighing ingredients in grams produces more consistent results.
