Teaspoons to Tablespoons Conversion
Convert teaspoons to tablespoons instantly with the calculator above, or browse the complete table below for every teaspoon value from 1 to 100. Because both units measure volume, the conversion is a fixed whole-number ratio: 3 teaspoons always equal 1 tablespoon in the US, UK, and metric systems. The single exception is Australia, where 1 tablespoon equals 4 teaspoons (20 mL). So 3 tsp = 1 tbsp, 12 tsp = 4 tbsp (1/4 cup), 24 tsp = 8 tbsp (1/2 cup), and 48 tsp = 16 tbsp (1 full US cup).

How to Convert Teaspoons to Tablespoons
Step 1: Use the Standard 3-to-1 Ratio
Teaspoons and tablespoons are both units of volume, and the relationship between them is set by definition almost everywhere in the world: 3 teaspoons make 1 tablespoon. This holds for US customary, UK Imperial, and metric measure. There’s no ingredient adjustment, no density factor, and no rounding error to worry about — the ratio is an exact whole-number relationship.
The single major exception is Australia, where the tablespoon was set at 20 mL when the country adopted the metric system in 1970. That’s 4 metric teaspoons, not 3. Australian recipes and measuring spoon sets follow this convention, while every other English-speaking country uses 3 tsp = 1 tbsp.
Step 2: Apply the Formula
To convert teaspoons to tablespoons, divide by 3:
For example, to convert 24 teaspoons (a common recipe amount):
That’s exactly half a US cup — which is why most baking recipes give measurements in multiples of 3 teaspoons. Bakers think in tablespoons; the teaspoon equivalent is just a finer-grained backup.
Quick mental math: Whole-tablespoon answers appear every 3 teaspoons (3, 6, 9, 12, 15, 18…). For non-multiples of 3, you’ll get a mixed form: 7 tsp = 2 tbsp + 1 tsp, 10 tsp = 3 tbsp + 1 tsp, 14 tsp = 4 tbsp + 2 tsp. This mixed form is often easier to measure than a fractional tablespoon.
Step 3: Worked Example — 24 Teaspoons to Tablespoons
Goal: Convert 24 teaspoons to tablespoons (a half-cup recipe amount).
1. Identify the ratio:
2. Apply the formula:
3. Calculate the result:
Answer: 24 teaspoons equals 8 tablespoons, which is exactly ½ cup or 4 US fluid ounces. This is one of the most commonly-encountered cooking conversions because half-cup amounts appear in nearly every dessert recipe.
Step 4: Reverse-Check Your Result
To verify, multiply your tablespoon answer by 3 and confirm you get back the original teaspoon value:
The round-trip is always exact because the conversion is a whole-number ratio — there’s no precision lost to rounding in either direction.
Step 5: Watch for the Australian Tablespoon
If you’re using an Australian cookbook or measuring-spoon set, the tablespoon is a different size: 20 mL = 4 metric teaspoons. To convert teaspoons to Australian tablespoons, divide by 4 instead of 3:
For 24 teaspoons that gives 6 Australian tablespoons, not 8. The calculator above includes a checkbox to toggle between the two systems. Default to the 3-tsp tablespoon unless your recipe was specifically written in Australia.
Rounding rules used on this page: Tablespoons appear as mixed fractions for the at-a-glance results and as decimals (to four places) for digital tools. The 3-to-1 ratio is exact — any rounding error comes from converting fractions to decimals, not from the conversion itself.

Units of Measurement
Teaspoons and tablespoons are both units of volume — they measure how much space a substance occupies, not how much it weighs. That’s why the conversion is identical for water, oil, flour, sugar, salt, or any other ingredient: 3 teaspoons of anything fills the same space as 1 tablespoon of anything. Ingredient density only matters when you’re converting between volume and weight (such as grams to teaspoons), not between two volume units.

What is a Tablespoon?
US tablespoon
= 14.7868 mL = 3 US teaspoons. The default tbsp in American recipes and measuring-spoon sets.
Metric tablespoon
= 15 mL = 3 metric teaspoons (5 mL each). Used across Europe and most of the world.
UK Imperial tablespoon
= 17.7582 mL = 3 UK teaspoons. Historical British value; modern UK recipes typically use metric.
Australian tablespoon
= 20 mL = 4 metric teaspoons. The global outlier — the only major tablespoon that isn’t 3 teaspoons.

Frequently Asked Questions
How many tablespoons are in a teaspoon?
One teaspoon equals 1/3 of a tablespoon (0.3333 tbsp). This works because, in US, UK, and metric measure, 3 teaspoons equal 1 tablespoon by definition.
How many teaspoons are in a tablespoon?
One tablespoon equals exactly 3 teaspoons in US, UK, and metric systems. In Australia, one tablespoon equals 4 metric teaspoons (20 mL).
What is the formula to convert teaspoons to tablespoons?
Divide the number of teaspoons by 3 to get tablespoons. For example, 12 teaspoons divided by 3 equals 4 tablespoons (which is also 1/4 cup). For Australian tablespoons, divide by 4 instead.
Does the teaspoons-to-tablespoons conversion change with the ingredient?
No. Both teaspoons and tablespoons are volume units, so the 3-to-1 ratio applies to every ingredient: water, oil, flour, sugar, salt, honey, vanilla extract, anything. Ingredient density only matters when converting between volume and weight (such as grams to teaspoons).
How many teaspoons are in a cup?
One US cup contains exactly 48 teaspoons (16 tablespoons). One metric cup (250 mL) contains 50 metric teaspoons. So 12 tsp = 1/4 cup, 24 tsp = 1/2 cup, 36 tsp = 3/4 cup, and 48 tsp = 1 cup.
What’s the difference between US, UK, metric, and Australian tablespoons?
The US tablespoon is 14.79 mL, the metric tablespoon is 15 mL, and the UK Imperial tablespoon is 17.76 mL — all three equal 3 teaspoons of their respective system. The Australian tablespoon is 20 mL and equals 4 metric teaspoons. So if your recipe is Australian, use the 4-to-1 ratio instead of 3-to-1.
How many milliliters is one teaspoon?
It depends on the system: US teaspoon = 4.92892 mL, metric teaspoon = 5 mL, UK Imperial teaspoon = 5.91939 mL. For most everyday cooking, the differences are small enough to ignore — treat 1 tsp as roughly 5 mL.
Is a dessertspoon the same as a tablespoon?
No. A UK dessertspoon equals 2 teaspoons (about 10 mL), which is halfway between a teaspoon and a tablespoon. Dessertspoons aren’t part of the standard US measuring-spoon set but appear in older British recipes and traditional dinnerware.
What’s the easiest way to measure fractional tablespoons?
Use the teaspoon equivalent instead. 1/3 tbsp = 1 tsp, 2/3 tbsp = 2 tsp. For 1 1/2 tbsp, measure 1 tbsp + 1 1/2 tsp. Most measuring-spoon sets give you cleaner increments in teaspoons than in fractional tablespoons.
How accurate are measuring spoons in real-world cooking?
Standard kitchen measuring spoons have a tolerance of about ±5 percent for liquids and ±10 percent for dry ingredients (depending on packing and levelling). For most cooking this is plenty; for baking and precision recipes, weighing on a digital scale is more reliable than measuring by volume.
