About the US tablespoons to US teaspoons converter
Tablespoon amounts often describe dressings, oils or a scaled recipe. A US tablespoon and an Australian tablespoon are different measures. Choose the convention in the source recipe and use level measuring spoons; a heaped spoon has no fixed volume.
One US tablespoon is exactly 3 US teaspoons, so 2 tbsp is 6 tsp. To convert tbsp to tsp, multiply by 3; to convert back, multiply by 0.3333333333.
The US tablespoon is half a fluid ounce, exactly 14.78676478125 mL. Because both units are defined exactly, the factor above is exact and the results here carry no conversion error.
