How to convert grams to teaspoons
A US teaspoon is about 4.93 mL, so teaspoons = grams ÷ (density × 4.93). For water (density 1), 5 g is about 1 teaspoon. Denser items like salt give fewer teaspoons per gram; lighter ones give more.
Worked example: 10 g of granulated sugar at 0.85 g/mL is 10 ÷ (0.85 × 4.93) = 2.39 teaspoons, while the same 10 g of flour at 0.53 g/mL comes to 3.8 teaspoons. The pattern is simple — the denser the ingredient, the fewer teaspoons a given weight fills.
The step behind the formula is a volume conversion: grams ÷ density gives millilitres, and millilitres ÷ 4.93 gives US teaspoons. Splitting it in two is useful when a recipe already quotes millilitres.

How to use this calculator
Enter the grams and the ingredient density. Density in g/mL: water 1, flour ~0.53, granulated sugar ~0.85, milk ~1.03, honey ~1.42, butter ~0.96. For larger amounts, the grams to tablespoons calculator is handier.
Densities to reuse (g/mL): water 1, milk 1.03, honey 1.42, vegetable oil 0.92, butter 0.96, granulated sugar 0.85, brown sugar 0.72, plain flour 0.53, cocoa powder 0.53, fine salt 1.2, baking powder 0.9. These are packed-as-normal figures; sifted flour is lighter and firmly packed brown sugar is heavier, which is why baking recipes that matter are written in grams.
Two practical notes. Spoon conversions suit small quantities such as spices, leavening and salt — above about 4 teaspoons switch to tablespoons, since 3 teaspoons make 1 tablespoon. And a level spoon is assumed throughout: a heaped teaspoon can hold half again as much, enough to matter for baking powder or yeast.

Frequently asked questions
- How many teaspoons is 5 grams?
- About 1 teaspoon for water; it varies by ingredient density.
- How many grams in a teaspoon?
- About 5 g of water, 4 g of sugar, or 6 g of salt — density dependent.
- How do I convert grams to teaspoons?
- Divide grams by the density times 4.93 (the mL in a US teaspoon).
- Is this a US teaspoon?
- Yes, 4.93 mL. A metric teaspoon is 5 mL.
- Why do salt and flour give different teaspoon counts for the same grams?
- Because a teaspoon measures volume, not weight, and ingredients differ in density. Fine salt packs at roughly 1.2 g/mL while flour sits near 0.53 g/mL, so 6 grams of salt fills about one teaspoon while 6 grams of flour fills more than two.
