Teaspoons to Tablespoons Conversion Chart for Your Kitchen
The One Rule That Solves 90% of Kitchen Conversions
In the United States, 1 tablespoon = 3 teaspoons. That single ratio handles nearly every recipe swap you'll ever need. If a recipe calls for 1 tablespoon of vanilla extract and you only have a teaspoon measure, level out 3 teaspoons and you're done.
The reverse works the same way: divide the number of teaspoons by 3 to get tablespoons. Six teaspoons of salt is 2 tablespoons. Nine teaspoons of baking powder is 3 tablespoons. Half a teaspoon is one-sixth of a tablespoon, which is why most cooks just measure it directly rather than trying to do the math.
The metric equivalents matter if you own a scale or a metric measuring spoon set. A US teaspoon holds 4.93 milliliters, and a US tablespoon holds 14.79 milliliters. Most American measuring spoons round those to 5 mL and 15 mL, which is close enough for everyday cooking.
Teaspoons to Tablespoons Conversion Chart
Use this chart for quick reference while cooking. All teaspoon values are US measurements.
| Teaspoons | Tablespoons | Milliliters | Common Use |
|---|---|---|---|
| 1 tsp | ⅓ tbsp | 5 mL | Ground spice, salt, vanilla |
| 2 tsp | ⅔ tbsp | 10 mL | Yeast, cocoa powder |
| 3 tsp | 1 tbsp | 15 mL | Olive oil, mustard, honey |
| 4 tsp | 1⅓ tbsp | 20 mL | Australian tablespoon equivalent |
| 6 tsp | 2 tbsp | 30 mL | Butter, sugar, lemon juice |
| 9 tsp | 3 tbsp | 45 mL | Milk, cream, cornstarch slurry |
| 12 tsp | 4 tbsp | 60 mL | ¼ cup — butter or oil |
| 15 tsp | 5 tbsp | 75 mL | Marinade base |
| 24 tsp | 8 tbsp | 120 mL | ½ cup — the common doubling target |
Notice the cup conversions in the last column. One cup equals 48 teaspoons, or 16 tablespoons. That connection is worth memorizing because it lets you scale a recipe up or down without measuring cups on hand.
Why Accuracy Matters More With Some Ingredients
For liquids like broth, oil, or vanilla, a slight measuring error rarely ruins a dish. Baking is different. Leavening agents are measured in fractions of a teaspoon, and the margin for error is small.
- Baking powder: Too much leaves a soapy, bitter aftertaste and causes the batter to rise then collapse. Stick to the exact amount in the recipe.
- Baking soda: Excess produces a metallic flavor and excessive browning. It also requires an acid to react, so adding more without more acid doesn't help.
- Salt: A recipe calling for 1 teaspoon of table salt will taste noticeably different if you substitute 1 teaspoon of coarse kosher salt, because the crystal size changes how much salt fits in the spoon. Diamond Crystal kosher salt measures about half as much by weight per teaspoon as table salt.
- Yeast: Active dry yeast is typically measured in 2¼ teaspoons, which equals three-quarters of a tablespoon. A standard packet contains exactly that amount.
How to Measure a Level Teaspoon Correctly
Recipes written by American cookbook authors assume you are using level, not heaped, measurements. Here's the technique that gives consistent results:
- Dip the spoon into the ingredient, then lift it out and sweep a straight edge (the back of a knife) across the top to remove the excess.
- For brown sugar, "packed" means you press the sugar into the spoon firmly with your thumb until it holds the spoon's shape when turned out.
- For flour, spoon it lightly into the measuring spoon rather than scooping directly from the bag. Scooping can compress the flour and add up to 20% more by weight.
- For liquids, hold the measuring spoon level over a bowl (not over the mixing bowl) so a spill doesn't land in your batter. Fill to the rim without letting the liquid dome above it.
If you bake frequently, a digital kitchen accurate to 0.1 grams removes the guesswork. For reference, 1 level teaspoon of table salt weighs about 6 grams, and 1 level teaspoon of granulated sugar weighs about 4 grams.
Watch Out for Australian Recipes
This is the most common conversion trap for US cooks. An Australian tablespoon is 20 milliliters, or 4 teaspoons — one-third larger than the American version. Australian, New Zealand, and many British recipes use the larger measure.
If you're making an Australian recipe with US measuring spoons, add one extra teaspoon for every tablespoon the recipe lists. A recipe calling for 2 Australian tablespoons of an ingredient needs 2 tablespoons plus 2 teaspoons in your American spoons, or 8 teaspoons total.
Scaling Recipes Up and Down
Once you're comfortable moving between teaspoons and tablespoons, doubling or halving a recipe becomes quick mental math.
- Doubling: 1½ tsp becomes 3 tsp, or 1 tablespoon. 2 tsp becomes 4 tsp, or 1⅓ tablespoons — just measure 4 teaspoons directly rather than trying to eyeball a third of a spoon.
- Halving: 1 tbsp becomes 1½ tsp. 2 tsp becomes 1 tsp.
- Tripling: 1 tbsp becomes 9 tsp, or 3 tablespoons.
When a conversion produces an awkward fraction like two-thirds of a tablespoon, convert to teaspoons instead and measure that. It's more precise than estimating a partial tablespoon.
A Quick Shortcut for Everyday Cooking
Keep a set of nested measuring spoons on a ring near your stove. Most sets include ¼ tsp, ½ tsp, 1 tsp, and 1 tbsp — four spoons that cover every conversion in the chart above. When a recipe needs 3 teaspoons, use the tablespoon spoon. When it needs 1½ teaspoons, combine the 1 tsp and ½ tsp. No calculations required.
Frequently Asked Questions
Q: How many teaspoons are in a tablespoon? A: 3 teaspoons in 1 US tablespoon. The metric equivalents are 5 mL per teaspoon and 15 mL per tablespoon, which is why metric spoon sets are labeled 5 mL and 15 mL.
Q: Is a tablespoon the same as a serving spoon? A: No. A regular dinner spoon holds roughly 1 tablespoon, but it isn't standardized. For baking and for any recipe where accuracy matters, use an actual measuring spoon. Flatware spoons vary in size from about 2.5 mL to 7 mL.
Q: Why does my recipe use "tbsp" and "t" — are those different? A: Yes. "Tbsp" or "TB" means tablespoon, and "t" or "tsp" means teaspoon. Some older recipes write them as a capital T and a lowercase t, so check carefully — confusing the two gives you three times more or less of an ingredient than intended.
