One Teaspoon equals 0.3333333333 Tablespoon (1 tsp = 0.3333333333 tbsp). Teaspoon to Tablespoon conversion comes up most often in baking spices and leavening and in liquid medicine dosing at home, typically when figures need restating for recipe oil and sauce quantities.
Precision and Rounding: US and imperial volume units share names but differ in size (an imperial gallon is about 20% larger than a US gallon), so confirm which system a figure uses before converting. Kitchen work tolerates rounding to the nearest milliliter or quarter-teaspoon; fuel, chemistry, and brewing need three or more decimal places.
