Teaspoons to Tablespoons Converter

How it works

US tablespoons = teaspoons ÷ 3 · other tablespoons = teaspoons × 4.929 mL ÷ tablespoon size in mL · cups = teaspoons ÷ 48 · fluid ounces = teaspoons ÷ 6 · weight = teaspoons × grams per teaspoon

Three teaspoons make one tablespoon, so for US measures you simply divide by 3: 6 teaspoons is 2 tablespoons and 4½ teaspoons is 1½ tablespoons. Spoons are not the same size everywhere, though. The US teaspoon is 4.93 mL and the metric teaspoon 5 mL, close enough to swap in everyday cooking; old British recipes used a 5.92 mL teaspoon and a 17.76 mL tablespoon. The Australian tablespoon is the odd one out at 20 mL, which is four teaspoons, not three. Pick your spoon in the unit menu (or type millilitres) and the tablespoon size in its menu, and the calculator converts through millilitres. You also get the amount as whole tablespoons plus leftover teaspoons, the nearest fraction, cups, fluid ounces and millilitres, a quick-reference chart and a table of spoon sizes from a smidgen to a tablespoon. Under More options you can pick an ingredient — salt, baking soda, yeast, sugar, flour, spices, oils or honey — to see what the amount weighs.

Worked example

A spice blend calls for 12 teaspoons in total. Dividing by 3 gives 12 ÷ 3 = 4 tablespoons, which is 12 ÷ 48 = 0.25 cups, 12 ÷ 6 = 2 fluid ounces and about 12 × 4.93 = 59 mL. If a recipe instead needs 5 teaspoons, that is 1⅔ tablespoons, measured as 1 tablespoon + 2 teaspoons. With an Australian 20 mL tablespoon, 12 US teaspoons (59 mL) is about 2.96 tablespoons.
