Quick answer: Divide teaspoons by 3 to get tablespoons. 3 teaspoons = 1 tablespoon. So 1 tsp = ⅓ tbsp, 1½ tsp = ½ tbsp, and 6 tsp = 2 tbsp.

Most baking and cooking recipes list spices and leavening in teaspoons, but batch cooking or ingredient prep often means scaling up to tablespoons to avoid counting three scoops at a time. The math is simple — 3 tsp always equals 1 tbsp — but the fractional amounts are where cooks get tripped up. For the reverse, the tablespoons to teaspoons converter handles tbsp → tsp.

Formula: Teaspoons to Tablespoons

tbsp = tsp ÷ 3

To go back from tablespoons to teaspoons, multiply by 3. All three of these are the same volume:

1 tablespoon
3 teaspoons
½ fluid ounce
14.787 mL

One teaspoon = 4.929 mL if you ever need to cross between teaspoons and milliliters.

Common Fractions and Their tsp Equivalents

Teaspoons	Tablespoons	Kitchen shorthand
¼ tsp	0.083 tbsp	¼ tsp (use ¼ tsp measure)
½ tsp	0.167 tbsp	½ tsp (use ½ tsp measure)
¾ tsp	0.25 tbsp	¾ tsp (use ¾ tsp measure)
1 tsp	⅓ tbsp	1 tsp (use 1 tsp measure)
1½ tsp	½ tbsp	½ tbsp
2 tsp	⅔ tbsp	2 tsp (no ⅔ tbsp measure)
3 tsp	1 tbsp	1 tbsp
4½ tsp	1½ tbsp	1 tbsp + 1½ tsp
6 tsp	2 tbsp	2 tbsp (= ⅛ cup)
9 tsp	3 tbsp	3 tbsp
12 tsp	4 tbsp	4 tbsp (= ¼ cup)
24 tsp	8 tbsp	8 tbsp (= ½ cup)
48 tsp	16 tbsp	16 tbsp (= 1 cup)

Tip: The ½ tbsp mark is the most useful conversion to remember — it equals 1½ tsp exactly. Many measuring spoon sets don't include a ½ tbsp, so knowing it equals 1½ tsp fills the gap.

Spice and Dry Ingredient Guide

When a recipe uses multiple teaspoons of the same spice, it's faster to reach for a tablespoon. Here's how common recipe amounts translate:

Common spice amounts

Recipe calls for	Tablespoon equivalent	Common in
1 tsp salt	⅓ tbsp	Bread, pasta dough
2 tsp baking powder	⅔ tbsp	Pancake batter, muffins
3 tsp chili powder	1 tbsp	Chili, taco seasoning
3 tsp cumin	1 tbsp	Indian and Mexican dishes
6 tsp paprika	2 tbsp	Dry rubs, stews
6 tsp garlic powder	2 tbsp	Marinades, spice blends
9 tsp sugar	3 tbsp	Salad dressings, glazes
12 tsp cornstarch	4 tbsp (= ¼ cup)	Gravies, puddings

Leavening agents (critical to measure carefully)

Baking soda and baking powder are measured in teaspoons and should never be eyeballed — too much causes a metallic taste, too little means flat results. Common amounts and their tablespoon equivalents:

Amount in tsp	In tbsp	Notes
¼ tsp baking soda	⅛ tbsp (= 0.083 tbsp)	Use ¼ tsp measure; no tbsp shortcut
½ tsp baking soda	⅙ tbsp	Use ½ tsp measure
1 tsp baking powder	⅓ tbsp	Use 1 tsp measure
2 tsp baking powder	⅔ tbsp	Use 1 tsp twice, or ½ + ¼ + ¼ tbsp
3 tsp baking powder	1 tbsp	1 tablespoon exact

Halving Recipes: Converting tsp to tbsp

When you cut a recipe in half, tablespoon amounts become odd fractions — and knowing how to get there through teaspoons makes measuring easier. Here's a quick reference for halved amounts:

Full recipe	Half recipe	How to measure
1 tbsp	½ tbsp = 1½ tsp	1 tsp + ½ tsp
2 tbsp	1 tbsp	1 tbsp
3 tbsp	1½ tbsp = 4½ tsp	1 tbsp + 1½ tsp
¼ cup (4 tbsp)	2 tbsp	2 tbsp
⅓ cup (5 tbsp + 1 tsp)	2 tbsp + 2 tsp	2 tbsp + 2 tsp
½ cup (8 tbsp)	4 tbsp = ¼ cup	¼ cup

When scaling recipes up or down, the mL to cups converter and the cups to mL converter are useful once amounts get large enough to measure in cups.

FAQs About Teaspoons to Tablespoons

How many teaspoons are in 1 tablespoon?

Exactly 3 teaspoons equal 1 tablespoon. This is true for US customary measurements. The UK tablespoon is slightly larger (15 mL vs 14.79 mL) but close enough that recipes work the same way in both countries.

Is ½ tablespoon the same as 1½ teaspoons?

Yes, exactly. Half a tablespoon (½ tbsp) = 1.5 teaspoons = 7.39 mL. Many measuring spoon sets don't include a ½ tbsp measure, so 1½ tsp (1 tsp + ½ tsp) is the practical way to measure it.

How many teaspoons in ¼ cup?

¼ cup = 4 tablespoons = 12 teaspoons. The hierarchy is: 1 cup = 16 tbsp = 48 tsp, so ¼ cup = 4 tbsp = 12 tsp.

Does 1 teaspoon = 5 mL?

For US cooking, 1 teaspoon = 4.929 mL — close to 5 mL but not exactly. For medical dosing, a "5 mL teaspoon" is the standard (a medicine dropper marked 5 mL). In the UK and Australia, the metric teaspoon is exactly 5 mL. In everyday cooking, the difference rarely matters.

How do I measure ⅔ tablespoon?

There is no ⅔ tablespoon measure. Use 2 teaspoons instead — 2 tsp = ⅔ tbsp (because 2 ÷ 3 = 0.667 tbsp). This is the practical kitchen solution.

What's the difference between a dry and liquid teaspoon?

There's no difference in volume — a teaspoon is a teaspoon regardless of what's in it. However, dry ingredients should be leveled (scooped and leveled off with a flat edge) while liquid ingredients fill to the meniscus. Flour measured by scooping and packing can be 30% more by weight than properly leveled flour, which is a recipe issue, not a unit issue.
