Convert Teaspoons to Grams: Water
Convert teaspoons of water to grams with this precise reference table. 1 teaspoon of water = 5g. There are 48 teaspoons in 1 US cup (240g) and 3 teaspoons in 1 tablespoon (15g). Teaspoon measurements are critical for accuracy when using water in small quantities — even a difference of 1g can matter in precise baking recipes.

Based on USDA FoodData Central data (1 US cup = 240ml = 16 tablespoons = 48 teaspoons). Note: Water is the reference point for all density measurements. 1 cup (240ml) = 240g exactly. All liquid measurements in recipes assume water-like density unless specified. Use water as baseline for density calculations.
About Water Density
The density of water determines how much it weighs per unit of volume. At 1g/ml, 1 US cup (240ml) of water weighs 240g under USDA standard conditions.
1 teaspoon = 1/48 cup = 5ml. For water, this equals 5g per teaspoon. Teaspoon measurements are critical for spices, extracts, and leavening agents where small differences have large effects. A kitchen scale is especially recommended for teaspoon-level precision.
Frequently Asked Questions
How many grams is 1 teaspoon of water?
1 teaspoon of water weighs approximately 5 grams (240g per cup ÷ 48 teaspoons per cup).
How many grams is 1/2 teaspoon of water?
1/2 teaspoon of water weighs approximately 2.5 grams.
How many teaspoons is 100g of water?
100g of water equals approximately 20 teaspoons.
Why is teaspoon-to-gram conversion important for water?
Small amounts like spices and leavening agents are often measured in teaspoons. For precision baking or cooking, knowing that 1 tsp of water = 5g helps avoid over- or under-measuring.
