Tablespoon to Teaspoon Converter
Convert tablespoons to teaspoons instantly. Free, bidirectional, and fully in-browser.
1 tablespoon equals 3 teaspoons — enter any tablespoon value to convert it to teaspoons instantly. This Tablespoon to Teaspoon converter is a client-side tool: it applies a single multiplication (tsp = tbsp × 3) in your browser, updates the moment you type, and works in both directions — edit either field, or press swap, to convert teaspoons back to tablespoons. A reference table lists common tablespoon values already converted, and nothing you enter is sent to a server.

A slider sets 0–10 decimal places, and very small or very large results switch to scientific notation instead of rounding to zero.

Frequently asked questions
How many teaspoons are in a tablespoon?
One tablespoon is 3 teaspoons. Multiply the tablespoon value by 3 to convert. For example, 10 tbsp = 30 tsp.
What is the formula to convert tablespoons to teaspoons?
tsp = tbsp × 3. This tool applies it automatically and shows a worked example: 10 tbsp = 30 tsp.
Can it convert teaspoons back to tablespoons?
Yes. Press the swap button, or type into the teaspoon field, and the tool converts teaspoons to tablespoons using the inverse of the same relationship.
Is the conversion accurate?
It uses the standard volume and capacity definition (tsp = tbsp × 3), not a rounded approximation, so results are exact to the number of decimal places you select.
Does this work offline and stay private?
Yes. The converter is a browser-side script with no network calls: your values are never uploaded, and once the page has loaded it keeps working without a connection.
