Grams to Teaspoons Converter

A US teaspoon is exactly 4.92892159375 mL. Three US teaspoons make one US customary tablespoon, and 48 make one US customary cup of exactly 236.5882365 mL. The calculator uses the full constants before rounding the displayed result.

Exactly 3 US teaspoons fit in 1 US tablespoon, and the calculator derives the tablespoon count straight from that ratio (tbsp = tsp / 3). The same rule holds for the UK metric tbsp at 15 mL (3 metric tsp of 5 mL), but the Australian tbsp is the outlier at 20 mL (4 metric tsp). If a recipe says 2 tbsp of sugar and you only have a teaspoon, that is 6 tsp by US measure, 8 tsp by Australian measure. Convert from the recipe origin, not from your spoon drawer.

Because density varies, and a US teaspoon is approximately 4.93 mL regardless of what it holds. Baking soda, baking powder, and table salt have different densities, so the same 5 g mass fills a different teaspoon volume. Weighing in grams removes that ambiguity.

There is no single international teaspoon. The US teaspoon is approximately 4.9289 mL, while the metric teaspoon used in the UK, Australia, New Zealand, India, and EU labeling is exactly 5 mL. The gap is small for cooking. For medication, follow the label in milliliters and use the supplied dosing device.

Whenever the ratio drives the result. Bread, cake, cookies, pastry, macarons, and chocolate work depend on the flour-to-fat-to-liquid balance, and a teaspoon-measured pinch of yeast, salt, or baking powder can swing 15 percent between heaped and level. The Bread Bakers Guild of America and King Arthur Baking both specify gram weights for every ingredient under 10 g (yeast, salt, leaveners, spice blends) for exactly that reason. For sourdough hydration, a 0.1 g resolution pocket scale lets you weigh 4 g of salt or 2 g of yeast directly, with the same number every time. Teaspoons remain fine for low-stakes cooking (soups, marinades, dressings) where a 10 percent variance in salt or spice does not change the dish.
