How Much Is 0.5 Teaspoons of Water in Grams?
0.5 teaspoons of water weighs 2.46 g. This is based on water having a density of 236.59g per cup. Because teaspoons measure volume and grams measure weight, the result depends on the ingredient, and a different ingredient would give a different result for the same 0.5 teaspoons.
Formula and Step-by-Step
- Start with 0.5 teaspoons of water
- 1 teaspoon of water = 4.93g
- 0.5 × 4.93 = 2.46g
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Mental Math Shortcut
Half measures: take the weight of 1 teaspoon (4.93g) and divide by 2.
Measuring Tip
Liquid densities vary: oils weigh less per cup than water, while syrups and honey weigh more. This is why ingredient-specific conversions matter even for liquids.
Water at Different Amounts

Understanding the Units
What is a Teaspoon?
A US teaspoon is 4.929 ml, a metric teaspoon is exactly 5 ml, and an imperial teaspoon is 5.919 ml. The metric and US versions are nearly identical (1.4% difference), but the imperial teaspoon is 20% larger. For most spices the difference is negligible, but for leaveners like baking powder it can affect the result.
What is a Gram?
Grams are the preferred unit in professional kitchens and bakeries because they allow exact recipe scaling. To double a recipe, simply double the gram values. No need to worry about how tightly an ingredient is packed into a cup.
