How many teaspoons are in a tablespoon? Quick conversion guide
There are 3 teaspoons in 1 US tablespoon. Use the chart for fractions, reverse conversions, metric equivalents and international spoon-size differences.
Tablespoons to teaspoons conversion chart
The standard US kitchen conversion is exact by volume: one tablespoon contains three teaspoons. The ingredient does not change the conversion, so a tablespoon of water, flour, oil or sugar is always the same volume even though each ingredient has a different weight.
Use the chart below for the portions most often found in recipes. Values such as 3/4 teaspoon may be measured with a 1/2-teaspoon spoon plus a 1/4-teaspoon spoon.
- 1/4 tablespoon = 3/4 teaspoon
- 1/3 tablespoon = 1 teaspoon
- 1/2 tablespoon = 1 1/2 teaspoons
- 2/3 tablespoon = 2 teaspoons
- 1 tablespoon = 3 teaspoons
- 1 1/2 tablespoons = 4 1/2 teaspoons
- 2 tablespoons = 6 teaspoons
- 3 tablespoons = 9 teaspoons
- 4 tablespoons = 12 teaspoons
- 16 tablespoons = 48 teaspoons = 1 US cup
How to convert tablespoons to teaspoons
Multiply the number of tablespoons by 3. For example, 2.5 tablespoons multiplied by 3 equals 7.5 teaspoons. The same calculation works for a whole number, fraction or decimal.
When a recipe calls for a fraction of a tablespoon, convert the fraction first or multiply it directly. One half times three is one and a half, so 1/2 tablespoon equals 1 1/2 teaspoons.
How to convert teaspoons to tablespoons
Divide the number of teaspoons by 3. Six teaspoons divided by 3 equals 2 tablespoons. Four teaspoons divided by 3 equals 1 1/3 tablespoons, which can also be measured as 1 tablespoon plus 1 teaspoon.
For kitchen use, it is often easier to keep any remainder in teaspoons. For example, 8 teaspoons can be written as 2 tablespoons plus 2 teaspoons instead of 2.666 tablespoons.
US, metric and Australian spoon sizes
US customary measures preserve the 3-to-1 relationship: an exact US tablespoon is about 14.79 milliliters and an exact US teaspoon is about 4.93 milliliters. In ordinary nutrition and kitchen guidance, these are commonly rounded to 15 milliliters and 5 milliliters. Standard metric measuring spoons use those rounded volumes, so one metric tablespoon also equals three metric teaspoons.
Australia is the important exception. An Australian tablespoon is commonly 20 milliliters, while its metric teaspoon is 5 milliliters. In an Australian recipe, one tablespoon can therefore mean four teaspoons. If a recipe's country of origin is unclear and the spoon quantity could affect the result, check the author's measurement notes.
- US customary: 1 tablespoon = 3 teaspoons = about 14.79 mL
- Standard metric: 1 tablespoon = 3 teaspoons = 15 mL
- Australian convention: 1 tablespoon = 4 teaspoons = 20 mL
Volume is not the same as weight
Tablespoons and teaspoons measure volume. Grams and ounces usually measure weight, so there is no single grams-per-tablespoon answer for every ingredient. A tablespoon of honey weighs more than a tablespoon of flour because their densities differ.
You can safely use the 3-to-1 spoon conversion for any ingredient, but use an ingredient-specific chart or a kitchen scale when converting spoon measures to grams. For precision-sensitive baking, weighing dry ingredients is usually more repeatable than filling small spoons.
Tips for accurate measuring
Use standardized measuring spoons rather than ordinary eating utensils, which vary widely. For flour, sugar, spices and other dry ingredients, fill the spoon and level the top with a straight edge unless the recipe specifically says heaping or rounded. For liquids, fill the spoon to the rim over a bowl or counter that can catch drips.
Do not use a kitchen teaspoon or tablespoon to measure medicine. Household spoons are not standardized, and even kitchen measuring spoons are less reliable than the dosing syringe or cup supplied with the medication. Follow the product label and a clinician's instructions.
Frequently asked questions
How many teaspoons are in half a tablespoon?
Half a tablespoon equals 1 1/2 teaspoons. You can measure it with one 1-teaspoon spoon plus one 1/2-teaspoon spoon.
How many teaspoons are in 2 tablespoons?
Two tablespoons equal 6 teaspoons because 2 multiplied by 3 is 6.
Is 1 teaspoon the same as 1/3 tablespoon?
Yes. In US and standard metric kitchen measures, 1 teaspoon is exactly one-third of a tablespoon.
How many tablespoons are 4 teaspoons?
Four teaspoons equal 1 1/3 tablespoons, or more practically, 1 tablespoon plus 1 teaspoon.
Does every country use 3 teaspoons per tablespoon?
Most US and metric recipes do, but Australia commonly uses a 20 mL tablespoon equal to four 5 mL teaspoons. Check the recipe's country when precision matters.
