How Many Tablespoons in a Cup? Measurement Chart

You are halfway through a recipe, you cannot find your measuring cup, but you have a tablespoon, so how many tablespoons in a cup? This tiny piece of kitchen maths saves countless recipes, and once you know the key numbers you can measure almost anything with just spoons. The answer is a tidy one to remember, and it links neatly to teaspoons and millilitres too. This guide gives you the core conversions, a handy chart for cup fractions, and a note on the difference between US and other tablespoons. For any measurement swap, our unit converter is ready to help, and it works alongside scaling a recipe up or down.

The key numbers

A few simple relationships unlock all kitchen spoon measuring:

So if a recipe needs a cup of an ingredient and you only have a tablespoon, you measure 16 level tablespoons. These numbers are worth memorising, as they cover the vast majority of measuring emergencies.

Cup fractions chart

Most recipes call for parts of a cup, so here is the quick reference:

Cup amount	Tablespoons	Teaspoons
1 cup	16 tbsp	48 tsp
3/4 cup	12 tbsp	36 tsp
1/2 cup	8 tbsp	24 tsp
1/3 cup	5 tbsp + 1 tsp	16 tsp
1/4 cup	4 tbsp	12 tsp

Notice that a third of a cup is not a whole number of tablespoons; it is 5 tablespoons plus 1 teaspoon, which is a common point of confusion.

Scale and convert

Our unit converter switches between spoons, cups, and millilitres, and our recipe scaler calculator adjusts a recipe for more or fewer servings.

Tablespoons in millilitres

If you prefer metric, a US tablespoon is about 15 millilitres and a teaspoon is about 5 millilitres. That keeps the ratio tidy: 3 teaspoons of 5 ml each make one 15 ml tablespoon. A US cup of 240 millilitres divided by 15 confirms the 16 tablespoons per cup. So you can move between spoons, cups, and millilitres using these round figures.

US vs other tablespoons

Be aware that the tablespoon is not identical everywhere. The US and UK tablespoon is about 15 millilitres, but the Australian tablespoon is 20 millilitres, equal to 4 teaspoons rather than 3. So an Australian recipe calling for a tablespoon means slightly more than a US one.

For most everyday cooking the difference is minor, but for baking or when a recipe uses several tablespoons, check which standard it follows. When in doubt, measure in millilitres to avoid ambiguity.

Frequently asked questions

How many tablespoons are in a cup?

There are 16 tablespoons in a US cup. This is a fixed conversion because both are volume measures. Since one tablespoon equals three teaspoons, a cup also equals 48 teaspoons. So to measure a cup using only a tablespoon, you would add 16 level tablespoons of the ingredient.

How many tablespoons are in half a cup?

There are 8 tablespoons in half a US cup, since a full cup is 16 tablespoons. That is also 24 teaspoons. For a quarter cup, it is 4 tablespoons, and for three-quarters of a cup, it is 12 tablespoons. These even fractions make spoon measuring straightforward for most recipe amounts.

How many tablespoons are in a third of a cup?

A third of a cup is 5 tablespoons plus 1 teaspoon. Unlike the halves and quarters, a third does not divide into a whole number of tablespoons, which surprises many cooks. In teaspoons, a third of a cup is 16 teaspoons. This is the one cup fraction worth remembering carefully.

How many teaspoons are in a tablespoon?

There are 3 teaspoons in one tablespoon. This is a fixed and very useful conversion: it means a tablespoon is triple a teaspoon, and a cup, at 16 tablespoons, is 48 teaspoons. In millilitres, a teaspoon is about 5 ml and a tablespoon about 15 ml, keeping the same 3-to-1 ratio.

Is a US tablespoon the same as an Australian one?

No. A US and UK tablespoon is about 15 millilitres, equal to 3 teaspoons, while an Australian tablespoon is 20 millilitres, equal to 4 teaspoons. So an Australian tablespoon is larger. For most cooking the difference is small, but for baking or recipes using several tablespoons, check which standard applies or measure in millilitres.

The bottom line

There are 16 tablespoons in a US cup, and since a tablespoon is 3 teaspoons, that is 48 teaspoons. Half a cup is 8 tablespoons, a quarter is 4, and a third is 5 tablespoons plus 1 teaspoon, the one to remember. A tablespoon is about 15 ml, but note the Australian tablespoon is 20 ml.
