ConverterTablespoons to Teaspoons Converter
Expand a U.S. tablespoon amount into teaspoons when dividing a recipe, setting out smaller measures, or working without a tablespoon measure.
Enter decimals, simple or mixed fractions, or scientific notation. Commas and negative quantities are rejected. Results display up to four decimals.
Multiply By Three
For U.S. measures, teaspoons = tablespoons x 3. One tablespoon is 3 teaspoons, 1/2 tablespoon is 1.5 teaspoons, and 1/3 tablespoon is 1 teaspoon.
Why The Smaller Unit Can Be Clearer
Teaspoons avoid awkward tablespoon fractions when splitting dressings, spice blends, or extracts. Keep the source recipe nearby and do not round a fractional teaspoon upward without considering the ingredient's strength.
The tool uses U.S. spoon definitions, not the larger Australian tablespoon convention.
