Teaspoon to Tablespoon Converter

What Is a Teaspoon?

The US teaspoon (tsp) equals approximately 4.929 mL. It is the smallest standard cooking measure, used for spices, extracts, and medication dosing.

What Is a Tablespoon?

The US tablespoon (tbsp) equals 3 teaspoons or approximately 14.787 mL. It is a fundamental cooking measurement in US recipes.

Teaspoon to Tablespoon Formula

The conversion formula is:

tablespoons = teaspoons ÷ 3 exact

3 US teaspoons = 1 US tablespoon, by definition.

Worked Example

Convert 6 teaspoon (6 teaspoons of sugar):

Calculate: 6 → 2 tablespoon

Common Use Cases

This conversion is needed regularly in:

Recipe substitution: When a recipe calls for tablespoons but you only have teaspoons (or vice versa), the 3:1 ratio is the solution. Need 2 tablespoons of olive oil? Use 6 teaspoons. Need ½ tablespoon of salt? Use 1½ teaspoons.
Scaling small-batch recipes: When halving or doubling recipes with small quantities, converting between spoon sizes avoids awkward fractions. "1½ tablespoons" becomes a clean "4½ teaspoons" — easier to measure with standard spoon sets.
Baking accuracy: In baking, small differences in leavening agents (baking powder, baking soda, yeast) significantly affect results. Converting between teaspoons and tablespoons ensures exact measurements — 1 tablespoon of baking powder is very different from 1 teaspoon.
Seasoning and spice measurement: Recipes from different sources may use different spoon sizes for the same spice. Converting ensures consistency: "1 tbsp garlic powder" = "3 tsp garlic powder" regardless of the source.

Frequently Asked Questions

Why is it 3 teaspoons per tablespoon?

The 3:1 ratio is a defined standard in the US measurement system: 1 tablespoon = ½ fl oz = 14.787 mL, and 1 teaspoon = ⅙ fl oz = 4.929 mL. Dividing 14.787 by 4.929 gives exactly 3. This ratio has been standardized in US cookbooks since the late 1800s through the work of Fannie Farmer.

Is the 3:1 ratio the same in all countries?

Yes for metric and US systems (both define 1 tbsp = 3 tsp), but the absolute sizes differ. US: 1 tbsp = 14.787 mL. Metric/UK: 1 tbsp = 15 mL. Australia: 1 tbsp = 20 mL (so Australian recipes use 4 tsp = 1 tbsp). Always check the recipe's origin.

How do teaspoons and tablespoons relate to cups?

1 cup = 16 tablespoons = 48 teaspoons. So ¼ cup = 4 tbsp = 12 tsp, ⅓ cup = 5⅓ tbsp = 16 tsp, and ½ cup = 8 tbsp = 24 tsp. These relationships are the foundation of all US recipe measurement conversions.

Does a "heaping" teaspoon equal a tablespoon?

Roughly, but not exactly. A heaping teaspoon (mounded above the rim) holds about 1.5–2 times a level teaspoon, so roughly 7–10 mL. A level tablespoon is 14.787 mL. Two heaping teaspoons approximately equal one tablespoon, but for precise baking, always use level measurements.
