Teaspoons to Tablespoons
Convert teaspoons (tsp) to tablespoons (tbsp) instantly. There are exactly 3 teaspoons in 1 tablespoon. This is a pure volume-to-volume conversion — ingredient type does not matter.
💡 How to Convert Teaspoons to Tablespoons
Converting teaspoons to tablespoons is the most fundamental kitchen measurement conversion. Both teaspoons and tablespoons are US customary units of volume — they measure the space an ingredient occupies, not its weight. The conversion factor is a simple whole number (3), making the math straightforward division.
To convert teaspoons to tablespoons, divide the number of teaspoons by 3:
Step 1: Count the number of teaspoons.
Step 2: Divide by 3.
Step 3: Express the result as a fraction for practical kitchen use.
Example — 3 tsp: 3 ÷ 3 = 1 tablespoon
Example — 6 tsp: 6 ÷ 3 = 2 tablespoons
Example — 1½ tsp: 1.5 ÷ 3 = 0.5 tablespoons = ½ tablespoon
The conversion works in reverse too: to convert tablespoons to teaspoons, multiply by 3. For example, 2 tablespoons × 3 = 6 teaspoons. This is especially useful when scaling recipes — if a recipe calls for ½ tablespoon but you only have a teaspoon, measure 1½ teaspoons instead.
How Many Teaspoons Are in 1 Tablespoon?
3 teaspoons = 1 tablespoon. This is the foundational conversion constant for small-volume kitchen measurements. One tablespoon also equals ½ fluid ounce, 1/16 of a cup, or approximately 15 milliliters. Memorizing "3 tsp = 1 tbsp" is the single most useful kitchen math fact.
How Many Teaspoons Are in ½ Tablespoon?
1½ teaspoons = ½ tablespoon. This comes up frequently in recipes that call for "half a tablespoon" of an ingredient. Since most measuring spoon sets include a ½ teaspoon but not a ½ tablespoon, measure 1 teaspoon plus ½ teaspoon to get the right amount.
How Many Teaspoons Are in 2 Tablespoons?
6 teaspoons = 2 tablespoons. Two tablespoons equals 1 fluid ounce or approximately 30 mL. This is a common measurement for salad dressing portions, butter pats (1 oz), and many sauce recipes.
How Many Teaspoons Are in 3 Tablespoons?
9 teaspoons = 3 tablespoons. When tripling a recipe that calls for 1 tablespoon, you need 3 tablespoons (9 teaspoons). Rather than scooping 9 teaspoons individually, it's far more efficient to use a tablespoon measure 3 times.
How Many Teaspoons Are in ¼ Cup?
12 teaspoons = 4 tablespoons = ¼ cup. This bridges the tsp-to-cup gap. If you don't have a ¼ cup measure, you can use 4 tablespoons or 12 teaspoons. This equivalency is essential for small-batch recipes like a single serving of cake batter or a marinade.
How Many Teaspoons Are in ⅓ Cup?
16 teaspoons = 5⅓ tablespoons = ⅓ cup. This is one of the trickiest conversions because 16 ÷ 3 = 5.333 tablespoons. In practice, measure 5 tablespoons plus 1 teaspoon. Refer to our tablespoons to cups converter for all fraction-based cup conversions.
How Many Teaspoons Are in ½ Cup?
24 teaspoons = 8 tablespoons = ½ cup. Half a cup is 4 fluid ounces or approximately 118 mL. While you'd never want to measure ½ cup using teaspoons (24 scoops!), knowing this relationship helps verify measurements when converting between units.
How Many Teaspoons Are in 1 Cup?
48 teaspoons = 16 tablespoons = 1 cup. The full chain: 1 cup = 16 tbsp = 48 tsp = 8 fl oz = 236.59 mL. Understanding this hierarchy lets you convert between any US volume unit mentally. Use our tablespoons-to-cups converter for larger volumes.

Common Spice & Ingredient Measurements
Teaspoons and tablespoons are the primary units for measuring spices, leavening agents, and flavor extracts. Here are the most common measurements used in American cooking, sourced from King Arthur Baking and the USDA FoodData Central:[4][5]
| Ingredient | Common Amount | Equivalent | Grams |
|---|---|---|---|
| Table salt | 1 tsp | ⅓ tbsp | ~6g |
| Baking powder | 1 tsp per cup flour | ⅓ tbsp | ~4g |
| Baking soda | ½ tsp per cup flour | ⅙ tbsp | ~3g |
| Vanilla extract | 1 tsp per batch | ⅓ tbsp | ~4g |
| Ground cinnamon | 1 tsp | ⅓ tbsp | ~2.6g |
| Active dry yeast | 2¼ tsp (1 packet) | ¾ tbsp | ~7g |
| Olive oil | 1 tbsp | 3 tsp | ~13.5g |
| Honey | 1 tbsp | 3 tsp | ~21g |
| Butter (melted) | 1 tbsp | 3 tsp | ~14g |
| Granulated sugar | 1 tsp | ⅓ tbsp | ~4g |
Notice that 1 teaspoon of different ingredients weighs different amounts — salt is 6g while cinnamon is only 2.6g. This is because teaspoons measure volume, not weight. For precise baking, convert to grams using our density-based converters.
Common Mistakes When Converting Teaspoons to Tablespoons
- Confusing tsp and tbsp abbreviations — This is the single most dangerous kitchen measurement error. Using tablespoons (tbsp) when a recipe calls for teaspoons (tsp) means you're adding 3 times the intended amount. For salt, this can ruin a dish. For baking soda, it can make food taste bitter and metallic. Always double-check which abbreviation the recipe uses.
- Using heaped teaspoons for baking — A heaped teaspoon can hold nearly twice as much as a level one. For cooking (soups, stews), a heaped teaspoon is usually fine. For baking (where precision matters), always level off with a straight edge — the difference between 1 tsp and 1 heaped tsp of baking powder can mean the difference between a fluffy cake and a collapsed one.
- Using silverware teaspoons instead of measuring spoons — A silverware teaspoon (the kind you stir coffee with) is not standardized. Silverware teaspoons typically hold between 2.5 mL and 7 mL — the standard is 4.93 mL. Always use a proper measuring spoon — the flat kind that nests in a set.
- Not knowing the ½ teaspoon measurement — The smallest standard US measuring spoon is ¼ teaspoon. Many recipes call for ½ tsp, ¼ tsp, or even ⅛ tsp. If your set doesn't include ⅛ tsp, fill the ¼ tsp halfway. For critical measurements like baking, a digital scale (accurate to 0.1g) is more reliable than fractional teaspoons.
What Is a Teaspoon?
A teaspoon (tsp) is a US customary unit of volume equal to ⅓ of a tablespoon, ⅙ of a fluid ounce, or 1/48 of a cup. One teaspoon equals precisely 4.92892 milliliters, but for FDA nutrition labeling purposes, one teaspoon is rounded to 5 milliliters.[1][2]
Teaspoons can be abbreviated as tsp, and are also sometimes written as t, ts, or tspn — for example, 1 teaspoon can be written as 1 tsp. The teaspoon should not be confused with a dessert spoon (10 mL, used in some British recipes) or a coffee spoon (2 mL, used for espresso). In pharmaceutical dosing, 1 teaspoon = 5 mL is the standard.
What Is a Tablespoon?
A tablespoon (tbsp) is a US customary unit of volume equal to 3 teaspoons, ½ fluid ounce, or 1/16 of a cup. One tablespoon equals precisely 14.7868 milliliters, but for FDA nutrition labeling purposes, one tablespoon is rounded to 15 milliliters.[2][3]
Tablespoons can be abbreviated as tbsp, and are also sometimes written as T, Tbls, or Tb — for example, 1 tablespoon can be written as 1 tbsp. The uppercase "T" versus lowercase "t" convention (T = tablespoon, t = teaspoon) is used in some cookbooks but is not universal — always check the recipe's key or legend.
In professional baking, tablespoon measurements are increasingly replaced by gram measurements for improved consistency. The NIST recommends weighing ingredients for accuracy.[4]
