How Much Is 1 Teaspoon of Water in Grams?
1 teaspoon of water weighs 4.93 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 1 teaspoon.
Formula and Step-by-Step
- Start with 1 teaspoon of water
- 1 teaspoon of water = 4.93g
- 1 × 4.93 = 4.93g
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Mental Math Shortcut
For 1 teaspoon of water, just remember: 4.93g. Double it for 2 teaspoons (9.86g), halve it for a half teaspoon (2.46g).
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.

Understanding the Units
What is a Teaspoon?
One teaspoon holds about 5 milliliters. There are 3 teaspoons in a tablespoon and 48 teaspoons in a cup. Teaspoon accuracy matters most with leaveners like baking powder and baking soda, where small differences affect rise and texture.
What is a Gram?
Weighing ingredients in grams eliminates the variability of volume measurements. A cup of flour can weigh anywhere from 120g to 160g depending on how it was scooped, but 120g of flour is always 120g of flour.
