Why are the gram-to-teaspoon ratios different for each ingredient?

Each ingredient has a different density. Water is about 4.9 g per teaspoon, while all-purpose flour is around 2.6 g per teaspoon because it is lighter and traps air. Dense ingredients like honey or salt pack more grams into the same teaspoon volume.

How many grams are in one teaspoon of sugar?

One teaspoon of granulated white sugar is approximately 4.2 grams. Brown sugar packs slightly differently at about 4.6 g per teaspoon.

How many grams are in one teaspoon of salt?

One teaspoon of fine table salt is approximately 6.0 grams. Coarse or kosher salt packs less, so values vary; this converter uses fine salt.

How many grams are in one teaspoon of flour?

One teaspoon of all-purpose flour is approximately 2.6 grams when spooned and leveled. Scooping directly from the bag can add 10–20%, so weighing is more reliable for baking.

Is a teaspoon the same size in all countries?

The US teaspoon is 4.93 mL. Most countries use a 5 mL metric teaspoon. The difference is small (about 1.4%), so this converter uses 5 mL as the standard teaspoon for simplicity.

Can I convert liquids like water or oil?

Yes. Water is approximately 4.9 g per teaspoon and vegetable oil is about 4.5 g per teaspoon. Both are included in the ingredient list.

The converter divides the gram weight by the ingredient's grams-per-teaspoon value.
Results appear in teaspoons and also in tablespoons for larger amounts.
Switch direction to convert teaspoons back to grams using the same density.

Use cases

Measure baking powder or baking soda by weight when a recipe lists grams.
Convert small amounts of spices, salt, or sugar without a volume measuring spoon.
Scale a recipe from metric (grams) to US teaspoon measurements.
Check how many teaspoons of honey or maple syrup a smoothie recipe calls for.
Quickly halve or double a recipe while staying in the most practical unit.
