Tsp to Grams
Free online tsp to grams converter with 18 ingredients. Select water, flour, sugar, salt, honey, butter and more to get precise gram measurements using density-based formulas for perfect cooking and baking.
About This Calculator
The Teaspoons to Grams converter is a precise cooking and baking tool that converts volume measurements (teaspoons) to weight measurements (grams) using ingredient-specific density formulas. Unlike simple volume-to-volume converters, this tool accounts for each ingredient's unique density — a teaspoon of honey weighs much more than a teaspoon of flour, and this converter handles that correctly.
The conversion uses the standard US teaspoon measurement of 4.929 mL. For each ingredient, the formula is: grams = teaspoons × 4.929 × density (g/mL). The density values come from standard food science references and cover 18 common kitchen ingredients including water, milk, all-purpose flour, granulated sugar, brown sugar, salt, honey, butter, vegetable oil, ground almonds, cacao powder, raw rice, rolled oats, jam, Nutella, maple syrup, and cream at two fat percentages.
Regional Notes
United States: The US teaspoon is 4.929 mL (approximately 5 mL for nutritional labeling). This calculator uses 4.929 mL, which matches standard US culinary measurement.
United Kingdom: The UK teaspoon is 5 mL. For UK recipes, the results are within 1.5% accuracy. Multiply the result by 1.014 (5 / 4.929) for complete precision if needed.
India and metric countries: Metric countries standardize on 5 mL per teaspoon. The results from this calculator are accurate within 1.5% for metric teaspoons, well within acceptable tolerance for cooking and baking.
Weight-based measurement is always more accurate than volume-based measurement for dry ingredients. Bakers worldwide prefer grams over teaspoons because gram measurements eliminate the variability of how ingredients settle in a spoon. This converter helps you follow any international recipe with confidence.
Frequently Asked Questions
How does the Teaspoons to Grams converter work?
Enter the number of teaspoons, select your ingredient from the dropdown list, and click Convert. The calculator multiplies the teaspoons by 4.929 mL per teaspoon and then by the ingredient's density in g/mL to give you the exact weight in grams.
How many grams are in a teaspoon?
The gram weight of one teaspoon depends on the ingredient. One teaspoon of water weighs approximately 4.93 grams, butter weighs about 4.73 grams, all-purpose flour weighs about 2.61 grams, and granulated sugar weighs about 4.17 grams. Always select the correct ingredient for accurate results.
What is the formula to convert teaspoons to grams?
The formula is: grams = teaspoons × 4.929 × density, where density is the ingredient's mass per unit volume in g/mL. For example, 2 teaspoons of honey (density 1.42 g/mL) = 2 × 4.929 × 1.42 = 14.0 grams.
Why do different ingredients give different gram weights for the same teaspoon volume?
Different ingredients have different densities — how tightly packed the molecules are. Water has a density of 1.0 g/mL, while flour is much lighter at 0.53 g/mL and honey is denser at 1.42 g/mL. This is why a teaspoon of honey weighs more than a teaspoon of flour.
Is this converter accurate enough for baking?
Yes, this converter uses scientific density values for each ingredient, making it highly accurate for cooking and baking. For best results, use the exact ingredient specified in your recipe and level off your teaspoon for consistent volume measurement.
How many grams is 1 teaspoon of sugar?
One teaspoon of granulated sugar weighs approximately 4.17 grams. Powdered sugar is lighter at about 2.8 grams per teaspoon, while brown sugar weighs about 4.0 grams per teaspoon. Use the ingredient selector to choose the correct type of sugar.
How many grams is 1 teaspoon of salt?
One teaspoon of table salt weighs approximately 6.0 grams. This is based on the density of salt (1.22 g/mL) multiplied by the volume of one teaspoon (4.929 mL). Different salt types like kosher or sea salt may have different densities.
Can I convert grams back to teaspoons?
Yes, use the reverse formula: teaspoons = grams / (4.929 × density). Simply divide your gram weight by 4.929 and then by the ingredient's density. For water, divide grams by 4.929; for other ingredients, use their specific density.
