There are 16 tablespoons in a US cup. That makes 3/4 cup 12 tablespoons, 1/2 cup 8, 1/4 cup 4 and 1/8 cup 2, while 2/3 cup is 10 tablespoons plus 2 teaspoons and 1/3 cup is 5 tablespoons plus 1 teaspoon.

Those numbers come straight from how US kitchen measures are built. A cup is 8 fluid ounces, a tablespoon is 1/2 fluid ounce, and a teaspoon is 1/3 of a tablespoon. Once you know those three facts, every conversion in a recipe turns into simple counting.

Keep this one near the stove. The milliliter column uses the US customary cup of about 236.6 mL, the figure NIST gives, rather than the rounder 240 mL cup used on nutrition labels.

The thirds are the only awkward rows. Sixteen does not divide evenly by three, so you end up with a leftover fraction of a tablespoon, and the cleanest way to measure that leftover is in teaspoons. Since a tablespoon holds 3 teaspoons, 1/3 of a tablespoon is exactly 1 teaspoon and 2/3 of a tablespoon is exactly 2 teaspoons. If you want the full breakdown of the smaller spoon, the teaspoon to tablespoon math follows the same rule of three.

Learn the 8 ounce cup first, since most other kitchen measurements and conversions hang off it.

How many tablespoons in half a cup?

There are 8 tablespoons in half a cup. That is also 4 fluid ounces and exactly one stick of butter, which is why butter wrappers are printed with 8 tablespoon marks. If a recipe asks for 1/2 cup of butter and you have sticks, just use one whole stick. The stick of butter markings turn every tablespoon amount of butter into a single knife cut.

Half a cup is also the measurement you are most likely to need by spoon, because a lot of recipes halve cleanly into it. If your 1/2 cup measure is in the dishwasher, count out 8 level tablespoons and you are there.

How many tablespoons in a third of a cup?

There are 5 tablespoons plus 1 teaspoon in a third of a cup. Written as a fraction, that is 5 1/3 tablespoons. Two thirds of a cup doubles it: 10 tablespoons plus 2 teaspoons, or 10 2/3 tablespoons.

In practice, most cooks round 1/3 cup to 5 tablespoons for savory food and nobody can taste the difference. That missing teaspoon is only about 6 percent of the total. For baking, where small amounts of oil, honey or melted butter change texture, measure the extra teaspoon.

A quick way to remember it: 1/3 cup is "five and one," 2/3 cup is "ten and two."

How many tablespoons in 3/4 cup?

There are 12 tablespoons in 3/4 cup, which equals 6 fluid ounces. You will rarely want to count out 12 separate spoonfuls, so build it from bigger pieces instead:

  • 1/2 cup plus 1/4 cup
  • 1/4 cup three times
  • 1 cup minus 4 tablespoons (handy when you are pouring from a full cup)
  • 1 1/2 sticks of butter, when the ingredient is butter

The "cup minus 4 tablespoons" trick works well with liquids. Fill a liquid measuring cup to the 1 cup line, then spoon out 4 tablespoons and you are left with 3/4 cup.

How do you measure tablespoons fast without counting every spoonful?

Counting 10 or 12 spoonfuls invites mistakes, especially if someone talks to you halfway through. These shortcuts keep it quick and accurate.

  1. Use the biggest measure that fits, then add spoons for the rest. For 10 tablespoons, scoop 1/2 cup (8 tablespoons) and add 2.
  2. Use the 1/8 cup measure if your set has one. It holds exactly 2 tablespoons, which halves the counting.
  3. Read the ounce lines on a liquid measuring cup. Each 1/2 fluid ounce is one tablespoon, so 3 tablespoons of oil sit at the 1 1/2 ounce line. Many cups also print a 2 tablespoon line near the bottom. The ounces to cups conversions line up neatly with this.
  4. Line up spoonfuls in a small dish and count before they go in the bowl. A mistake caught in a ramekin is easy to fix; one in the batter is not.
  5. Weigh it instead. If you know what a tablespoon of the ingredient weighs, a scale reads the total in one pour.

For anything you measure often in baking, weight is the fastest route of all. A kitchen scale beats measuring cups whenever you are scaling a recipe or working with flour, because one number replaces a stack of spoons.

What's the difference between a dry vs liquid tablespoon?

The volume is identical. A tablespoon is a tablespoon whether it holds flour or milk, and there is no separate "dry tablespoon" unit. What changes is how you fill it.

  • Dry ingredients. Dip or spoon the ingredient in until it mounds, then sweep it level with the back of a knife. A heaped tablespoon can hold nearly twice what a level one does.
  • Liquids. Hold the spoon flat over a small bowl, not over your batter, and fill it right to the rim. The liquid should sit flat or bulge slightly without spilling.
  • Sticky ingredients. Coat the spoon lightly with oil or cooking spray before measuring honey, molasses or peanut butter so the full amount slides out.
  • Packed ingredients. Brown sugar and shortening get pressed into the spoon so there are no air pockets, then leveled.

When a recipe says "heaping" or "rounded," the writer is telling you not to level. Those amounts are loose by design. For very small pinches, the pinch, dash and smidgen measures are looser still.

How many grams in a tablespoon?

It depends on the ingredient, because grams measure weight and tablespoons measure volume. Water is the easy case: a US tablespoon of water is about 14.8 mL, so it weighs about 15 grams. Everything else needs a per-ingredient number.

Water or milk237 to 24015
All-purpose flour, spooned and leveled1207.5
Granulated sugar19812.4
Butter22714

The flour, sugar and butter cup weights follow King Arthur Baking's ingredient weight chart; the tablespoon column is simply the cup weight divided by 16. Other references put a cup of flour anywhere from about 120 to 130 grams, so a tablespoon of flour lands at roughly 7.5 to 8 grams depending on whose numbers you follow. If a recipe gives grams, use them. The grams in a cup of flour change a lot with how you fill the cup, which is why weight is more reliable.

Spices and salt vary even more. Fine table salt packs densely, while flaky salt and fluffy dried herbs are mostly air, so the same tablespoon can weigh very different amounts. That is also why swapping dried herbs for fresh uses a ratio of volume rather than a straight swap.

Is a tablespoon the same everywhere?

Not quite. The difference shows up when you cook from recipes written outside the US.

  • US customary tablespoon: about 14.8 mL, with 16 to a 236.6 mL cup.
  • US nutrition label tablespoon: 15 mL, since the FDA defines a cup as 240 mL for labeling.
  • Metric tablespoon (UK, Canada, New Zealand and others): 15 mL, with a metric cup of 250 mL.
  • Australian tablespoon: 20 mL, or 4 teaspoons rather than 3.

For a single tablespoon of vanilla or soy sauce, the gap between 14.8 and 15 mL is meaningless. The Australian tablespoon is the one to watch, because using a US spoon for an Australian recipe gives you only about three quarters of what was intended. A metric cup of 250 mL also holds closer to 17 US tablespoons than 16, which matters more when a recipe calls for several cups. The US cup vs metric cup difference adds up across a whole batch of cake batter.

My half batch came out wrong: where did the tablespoons go?

Halving and thirding recipes is where tablespoon math trips people up. These are the usual symptoms and what causes them.

What you seeLikely causeFix
Cookies spread or cake is greasy after halvingHalved 1/3 cup butter as "2 tablespoons" instead of 2 tablespoons plus 2 teaspoonsHalf of 1/3 cup is 1/6 cup: 2 tbsp + 2 tsp
Sauce too thin in a third batchRounded 1/3 of 1/4 cup (4 tbsp) down to 1 tablespoonA third of 4 tbsp is 1 tbsp + 1 tsp
Batter dry and stiffHeaped tablespoons of flour instead of levelingSpoon in, sweep level, or weigh at 7.5 g per tbsp
Dressing tastes sharpUsed an Australian 20 mL spoon or a big serving spoonUse a true US measuring spoon, 14.8 mL
Honey amount looks shortHoney stayed stuck in the spoonOil the spoon first and scrape it clean

The safest way to halve or third an amount is to convert it all the way down to teaspoons first. One cup is 48 teaspoons, so any fraction of a cup becomes a whole number of teaspoons that you can divide, then turn back into tablespoons. For example, 2/3 cup is 32 teaspoons; half of that is 16 teaspoons, which is 5 tablespoons plus 1 teaspoon.

Can you measure a cup with a tablespoon if you have no measuring cup?

Yes, as long as you have a real measuring spoon. Sixteen level tablespoons make one cup, and it is accurate enough for nearly any recipe. Counting gets tedious past a half cup, so for bigger amounts it is faster to use a known container. Most mugs and glasses are not marked, but any container labeled 8 fluid ounces holds exactly 1 cup.

Avoid using eating spoons from the silverware drawer as a stand-in. Tableware "tablespoons" and soup spoons vary widely in size, and none of them are made to a standard volume. For salt, baking soda and baking powder, that variation is enough to change how a recipe tastes or rises.

Watch tablespoons fill a cup

Watching someone level dry spoonfuls and fill liquid ones to the rim makes the 16 tablespoon count easier to trust. It also shows how much a heaped spoon differs from a level one.

What to watch for
  • Count the level spoonfuls going into the cup and check that it takes 16 tablespoons to reach the 1 cup line.
  • Notice how a dry tablespoon is swept flat, which keeps a tablespoon of flour near 7.5 grams instead of nearly double.
  • Look at where 8 tablespoons land on a liquid cup, right at the 4 ounce or 1/2 cup mark.
