Try MealMatics FreeHow to Convert Teaspoons to Tablespoons
We get this question constantly and the answer is almost disappointingly simple: three teaspoons per tablespoon, every time, no exceptions. NIST Handbook 44 puts the US teaspoon at 4.929 millilitres and the tablespoon at 14.786 — exactly three times the teaspoon.
Six teaspoons is 2 tablespoons, nine is three, and the only fraction most people ever need is 1.5 teaspoons for half a tablespoon. Unlike cups-to-grams, this ratio never changes — cinnamon, salt, baking powder, vanilla extract, all the same.
Spices are where this conversion actually matters, because measurement errors compound fast. Add one extra teaspoon to a recipe calling for 1 tablespoon of cayenne and you have boosted the heat by 33 percent — the difference between seconds and reaching for the milk carton.
The common amounts work out cleanly: 1.5 tablespoons of smoked paprika is 4.5 teaspoons, half a tablespoon of cumin is 1.5 teaspoons, 2 tablespoons of chili powder is 6 teaspoons. For small spice amounts, the 3-to-1 ratio handles the precision you actually need.
