Why Grams to Teaspoon Differs by Ingredient
A teaspoon is a unit of volume (~4.93 mL), whereas a gram is a unit of mass/weight. Therefore, 1 tsp of dense table salt weighs ~5.7g, whereas 1 tsp of airy powdered flour weighs only ~2.6g.

How Metric Teaspoon Converter Works?
The Metric Teaspoon Converter works by dividing a gram weight by the weight of the ingredient in a 5.00 mL metric teaspoon. The metric spoon holds 1.4% more than a US spoon, so each metric teaspoon weighs 1.4% more.

Read metric spoons
Enter grams or metric teaspoons. Results show decimals, spoon fractions and metric tablespoons of 15 mL.
Metric Teaspoon Converter Formula
The Metric Teaspoon Converter formula is metric tsp = grams ÷ (density × 5 mL). Converting a US teaspoon value to metric means multiplying by 5 ÷ 4.92892 = 1.0144.
g per metric tsp = g per US tsp × 1.0144 | metric tsp = g ÷ (ρ × 5)
- Granulated sugar: 4.17 × 1.0144 = 4.23 g per metric tsp.
- 20 g of water ÷ 5 g = 4 metric tsp.
- 1 metric tbsp (15 mL) = 3 metric tsp in the UK, Canada and New Zealand.

What is Metric Teaspoon Converter?
The Metric Teaspoon Converter is a grams-to-teaspoons calculator based on the 5.00 mL metric teaspoon. The metric teaspoon is the standard spoon in countries that use the International System of Units (SI) for cooking.
Metric spoons pair with a 15 mL tablespoon in most countries and a 20 mL tablespoon in Australia, plus a 250 mL cup. A metric teaspoon of water weighs 5 g, which makes mental checks easy: 10 mL of a water-thin liquid weighs about 10 g and fills 2 metric teaspoons.
What are the uses of Metric Teaspoon Converter?
There are 4 main uses of the Metric Teaspoon Converter: following UK, Canadian and Australian recipes, measuring medicine-style liquids, converting European recipes, and teaching SI units.
Commonwealth recipes
British, Canadian and Australian recipes assume 5 mL spoons. The converter gives grams for those spoons.
Liquid doses
Oral syringes and dosing cups use 5 mL units. The converter shows the gram weight of 1 metric teaspoon of a syrup.
European recipes
Cookbooks from Germany, France and Italy list "1 TL" or "1 c. à café" for a 5 mL spoon.
SI teaching
Science teachers use the 5 mL spoon to link millilitres, grams and density in a single measurement.
Metric Teaspoon Converter Measuring Tips
- A metric teaspoon is rounded to exactly 5.00 millilitres.
- Slightly larger than a US teaspoon (~1.4% increase in volume).
