Tablespoons to Cups
Convert tablespoons (tbsp) to cups (c) instantly. There are exactly 16 US tablespoons in 1 US customary cup. This is a pure volume-to-volume conversion โ ingredient type does not matter.
๐ก How to Convert Tablespoons to Cups
Converting tablespoons to cups is one of the most common kitchen measurement tasks in American cooking. Both tablespoons and cups are US customary units of volume โ they measure the space an ingredient occupies, not its weight. Because the conversion factor is a fixed whole number (16), the math is simple division.
To convert tablespoons to cups, divide the number of tablespoons by 16:
Step 1: Count the number of tablespoons.
Step 2: Divide by 16.
Step 3: Express the result as a fraction for practical kitchen use.
Example โ 8 tbsp: 8 รท 16 = 0.5 cups = ยฝ cup
Example โ 5 tbsp: 5 รท 16 = 0.3125 cups โ โ cup (precisely โ cup minus 1 tsp)
Example โ 24 tbsp: 24 รท 16 = 1.5 cups = 1ยฝ cups
The conversion works in reverse too: to convert cups to tablespoons, multiply by 16. For example, ยพ cup ร 16 = 12 tablespoons. When scaling a recipe, it's often easier to convert everything to tablespoons first, scale, then convert back to cups.
How Many Tablespoons Are in 1 Cup?
16 tablespoons = 1 cup. This is the foundational conversion constant for US customary volume measurements. One cup also equals 8 fluid ounces, 48 teaspoons, or 236.588 milliliters. If a recipe calls for "1 cup of sugar," you can measure it as 16 level tablespoons instead.
How Many Tablespoons Are in ยพ Cup?
12 tablespoons = ยพ cup. This is one of the most commonly searched kitchen conversions. Three-quarters of a cup equals 12 tablespoons, 6 fluid ounces, or 177.44 mL. If you don't have a ยพ cup measuring cup, scoop 12 level tablespoons.
How Many Tablespoons Are in โ Cup?
10 tablespoons + 2 teaspoons = โ cup. This is the trickiest common fraction because โ of 16 is 10.667 โ not a whole number. The precise answer is 10โ tablespoons, which equals 10 tablespoons plus 2 teaspoons. When a recipe calls for โ cup of flour, use this exact measurement for best results.
How Many Tablespoons Are in ยฝ Cup?
8 tablespoons = ยฝ cup. Half a cup is exactly 8 tablespoons, 4 fluid ounces, or 118.29 mL. This is also the volume of 1 stick of butter (4 oz / 113g). If you're halving a recipe that calls for 1 cup, measure 8 tablespoons.
How Many Tablespoons Are in โ Cup?
5 tablespoons + 1 teaspoon = โ cup. Like โ cup, this is not a clean conversion because โ of 16 is 5.333. The precise answer is 5โ tablespoons, which equals 5 tablespoons plus 1 teaspoon. This measurement comes up frequently in baking recipes.
How Many Tablespoons Are in ยผ Cup?
4 tablespoons = ยผ cup. One-quarter cup is exactly 4 tablespoons, 2 fluid ounces, or 59.15 mL. This is a clean, easy conversion. Many recipes for small batches โ like a single serving of salad dressing or a marinade โ use ยผ cup measurements.
How Many Tablespoons Are in โ Cup?
2 tablespoons = โ cup. One-eighth of a cup is exactly 2 tablespoons, 1 fluid ounce, or 29.57 mL. Most measuring cup sets don't include a โ cup measure, so this conversion to tablespoons is essential.
How Many Tablespoons Are in 2 Cups?
32 tablespoons = 2 cups. Two cups is 1 pint, 16 fluid ounces, or 473.18 mL. When doubling a recipe, you'll often need to know that 2 cups requires 32 tablespoons. Use our recipe scale calculator for complex scaling.

The Complete US Volume Measurement Hierarchy
Understanding how US customary volume units relate to each other is essential for any American cook. Every unit in the chain divides evenly into the next โ making mental math possible once you memorize the ratios:[3]
| Unit | Teaspoons | Tablespoons | Fluid Ounces | Cups |
|---|---|---|---|---|
| 1 teaspoon | 1 | โ | โ | 1/48 |
| 1 tablespoon | 3 | 1 | ยฝ | 1/16 |
| 1 fluid ounce | 6 | 2 | 1 | โ |
| ยผ cup | 12 | 4 | 2 | 0.25 |
| ยฝ cup | 24 | 8 | 4 | 0.5 |

US Cup vs. Metric Cup vs. Australian Cup
If you're following a recipe from an international blog, cookbook, or YouTube channel, the "cup" they reference may not be the same size as a US cup. This is one of the most common sources of baking failures for American cooks following non-US recipes.[2]
| Cup Type | Volume (mL) | Difference vs US Cup | Where Used |
|---|---|---|---|
| US customary cup | 236.588 mL | โ | United States |
| US legal cup (FDA) | 240 mL | +1.4% | US nutrition labels |
| Metric cup | 250 mL | +5.7% | UK, Canada, most countries |
| Australian cup | 250 mL | +5.7% | Australia, New Zealand |
| Japanese cup | 200 mL | โ15.5% | Japan |
A 5.7% difference (US vs metric) may seem small, but in baking it compounds across multiple ingredients. If an Australian recipe calls for 3 cups of flour and you use US cups, you'll have about 40 mL (nearly 3 tablespoons) less flour than intended โ enough to noticeably change the texture of a cake. When following international recipes, always check which cup standard is being used, or better yet, convert to grams for precision.
Common Mistakes When Converting Tablespoons to Cups
- Using heaped tablespoons instead of level โ A heaped tablespoon can hold 25โ50% more ingredient than a level one. Always level off dry ingredients with a straight edge (a knife or the back of a spatula) for an accurate 15 mL measurement.
- Confusing tablespoons (tbsp) with teaspoons (tsp) โ 1 tablespoon = 3 teaspoons. Accidentally using teaspoons when a recipe calls for tablespoons means you're using only โ of the required amount. This is the single most common measurement error in home cooking.
- Using a dinner spoon instead of a measuring tablespoon โ Dining tablespoons are not standardized. They range from 7 mL to 20 mL depending on the design. Always use a proper measuring spoon โ the flat kind that nests, not silverware.
- Not accounting for US vs metric cups โ If you're following a recipe from the UK, Canada, or Australia, their "cup" is 250 mL, not 236.6 mL. Over 3 cups, that's a difference of ~40 mL (3 tablespoons). Use grams-based conversion for international recipes.
What Is a Tablespoon?
A tablespoon (tbsp) is a US customary unit of volume equal to 3 teaspoons, ยฝ fluid ounce, or 1/16 of a cup. One tablespoon equals precisely 14.7868 milliliters, but for FDA nutrition labeling purposes, one tablespoon is rounded to 15 milliliters.[1][2]
Tablespoons can be abbreviated as tbsp, and are also sometimes written as T, Tbls, or Tb โ for example, 1 tablespoon can be written as 1 tbsp. In scientific and pharmaceutical contexts, the tablespoon is sometimes written as 15 mL. The tablespoon should not be confused with the dessert spoon (10 mL), which is used in some British and Commonwealth recipes.
What Is a Cup?
A cup (c) is a US customary unit of volume equal to 16 tablespoons, 8 fluid ounces, or 48 teaspoons. One US customary cup equals precisely 236.588 milliliters, but for FDA nutrition labeling, one cup is defined as 240 milliliters.[2]
The cup should not be confused with the metric cup (250 mL), the Japanese cup (200 mL), or the teacup (which has no standardized volume). Cups can be abbreviated as c or C โ for example, 1 cup can be written as 1 c.
In professional baking, cups are increasingly being replaced by gram measurements because a "cup of flour" can weigh anywhere from 120g to 150g depending on how it's scooped โ a 25% variation that can ruin a recipe. The NIST recommends weighing ingredients for accuracy.[3]
