How to Use This Converter
Enter an amount, choose your starting unit, and the converter shows the equivalent in cups, tablespoons, teaspoons, and milliliters instantly. Works in both directions — convert cups to tablespoons or tablespoons back to cups.
How Many Tablespoons in a Cup?
There are 16 tablespoons in 1 US cup. This is one of the most useful kitchen conversions for scaling recipes when you're missing the right measuring cup. Quarter cup is 4 tablespoons, third cup is 5 tablespoons plus 1 teaspoon, and half cup is 8 tablespoons.
Why ⅓ Cup Is an Odd Number of Tablespoons
Most cup fractions divide evenly into tablespoons — except ⅓ cup. Because 16 tablespoons doesn't divide evenly by 3, one third of a cup equals 5 tablespoons plus 1 teaspoon (5.333 tablespoons). Similarly, ⅔ cup = 10 tablespoons plus 2 teaspoons. This is why recipes sometimes list ⅓ cup rather than trying to express it in tablespoons.
When This Conversion Comes Up Most
The cups-to-tablespoons conversion is most useful in three situations. First, when a recipe calls for a small amount in cups (like ¼ cup of olive oil) and you'd rather grab the tablespoon measure instead. Second, when scaling a recipe down — if you're halving a recipe that calls for ¾ cup of something, knowing that's 12 tablespoons (and half is 6 tablespoons) is faster than looking for the ⅜ cup mark. Third, when your measuring cup is dirty or missing and tablespoon is what you have.
For converting cups to grams for specific ingredients like flour, sugar, or butter, use the Cups to Grams Calculator instead — volume-to-weight depends on the ingredient's density.
Frequently Asked Questions
How many tablespoons is ¼ cup?
¼ cup equals exactly 4 tablespoons. This comes up frequently in recipes that call for a small amount of butter, oil, or liquid. Four tablespoons is also equal to 2 fluid ounces or 60ml.
How many tablespoons is ½ cup?
½ cup equals 8 tablespoons. For butter, ½ cup is also 1 stick of US butter (113g / 4 oz). If a recipe calls for ½ cup of butter and you're measuring by tablespoon, count out 8.
How many tablespoons is ¾ cup?
¾ cup equals 12 tablespoons. Three-quarters of 16 is 12. In teaspoons that's 36 — but at that volume it's more practical to use tablespoons or the ¾ cup measure directly.
How many tablespoons is ⅛ cup?
⅛ cup equals 2 tablespoons exactly. This comes up with spices, extracts, and small amounts of oil or vinegar in dressings and marinades.
Are cups and tablespoons the same in all countries?
No. This converter uses US measurements: 1 US cup = 240ml, 1 US tablespoon = 14.79ml, so 1 cup = 16 tablespoons. Australian tablespoons are 20ml, making 1 cup about 12 Australian tablespoons. UK and Canadian cups are slightly different from US cups. For international recipes, check which country's measurements the recipe uses before converting.
Worked Example: Scaling a Recipe Down
Say a recipe calls for ¾ cup of olive oil, but you want to make just a third of the batch. ¾ cup = 12 tablespoons, so a third of that is 4 tablespoons — much easier to measure out precisely than trying to eyeball ¼ cup on a measuring cup that isn't marked in thirds. This is the core reason tablespoon conversions matter: they let you scale awkward cup fractions into a unit that divides more cleanly.
How many tablespoons is ⅔ cup?
⅔ cup equals 10 tablespoons plus 2 teaspoons (10.67 tablespoons). Like ⅓ cup, this doesn't divide evenly into whole tablespoons, which is why recipes typically express it as a cup fraction rather than a tablespoon count.
How many tablespoons is 1 cup?
1 cup equals 16 tablespoons exactly. This is the anchor figure all other cup-to-tablespoon conversions are derived from — multiply the cup fraction by 16 to get the tablespoon equivalent.
Tablespoons vs Cups: Which to Use When
Tablespoons are the better choice for amounts under ¼ cup, where a cup measure would force you to guess at a fraction of a fraction. Cups are better for anything ½ cup or larger, since counting out 8+ tablespoons is slower and introduces more room for miscounting than reading a marked cup line. As a practical threshold: below 4 tablespoons, reach for the tablespoon; at 4 tablespoons (¼ cup) or more, switch to a cup measure if one is available.
Does it matter which one I use if the math is the same?
For most recipes, no — 4 tablespoons and ¼ cup are exactly the same amount, so the tool is purely convenience and precision, not accuracy. The one exception is when you're counting many tablespoons (8 or more), where a small measuring error per spoonful compounds across repetitions; a cup measure filled once is less error-prone at that scale.
