How Many Tablespoons in a Cup?
There are exactly 16 tablespoons in 1 US cup. This is one of the most important kitchen measurement conversions, and it applies to both liquid and dry ingredients measured by volume. To convert tablespoons to cups, divide the number of tablespoons by 16. To go the other direction, multiply cups by 16.
This 16-to-1 ratio creates several convenient fractions that you will use regularly in the kitchen:
- 2 tablespoons = 1/8 cup (1 fluid ounce)
- 4 tablespoons = 1/4 cup
- 5 tbsp + 1 tsp = 1/3 cup
- 8 tablespoons = 1/2 cup
- 12 tablespoons = 3/4 cup
- 16 tablespoons = 1 cup
Memorizing even a few of these fractions will speed up your cooking and reduce the number of measuring tools you need to wash. If you know that 4 tablespoons is a quarter cup, you can quickly measure 1/4 cup of oil without reaching for the cup measure.
Butter Stick Measurements
One of the most common tablespoon-to-cup conversions involves butter. In the United States, butter is sold in sticks, and each stick has a standardized size that maps neatly to tablespoon and cup measures:
- 1 stick of butter = 8 tablespoons = 1/2 cup = 4 oz (113 g)
- 1/2 stick of butter = 4 tablespoons = 1/4 cup = 2 oz (57 g)
- 2 sticks of butter = 16 tablespoons = 1 cup = 8 oz (227 g)
Most butter wrappers in the US are printed with tablespoon markings along the side, making it easy to cut off exactly the amount you need. If your wrapper does not have markings, each stick is approximately 12 cm (4.75 inches) long, so each tablespoon mark would be about 1.5 cm apart.
When a European or international recipe calls for butter in grams, remember that 1 tablespoon of butter weighs approximately 14 grams. This can help you convert between volume-based American recipes and weight-based European ones without a scale.
How to Convert Tablespoons to Cups
The conversion formula is straightforward: divide the number of tablespoons by 16. For example, 24 tablespoons divided by 16 equals 1.5 cups. You can also think of it in terms of fractions: each tablespoon is 1/16 of a cup, so 5 tablespoons is 5/16 of a cup.
For amounts that do not divide evenly into 16, the result will be a decimal. In those cases, it is usually more practical to keep the measurement in tablespoons. For instance, 7 tablespoons is 0.4375 cups — there is no standard measuring cup for that amount, so just use 7 tablespoons.
However, when the result is a common fraction (1/4, 1/3, 1/2, 2/3, 3/4), switching to the cup measure is more convenient and faster. This is especially true for larger quantities — measuring out 12 tablespoons one at a time is tedious when you could just pour 3/4 cup.
Baking Conversions and Quick Reference
In baking, accuracy matters more than in general cooking. Here are some practical tips for tablespoon-to-cup conversions in baking contexts:
Flour: 1 cup of all-purpose flour is about 125 grams. If you need to add 2 tablespoons (about 16 grams), it is not worth switching to a cup measure — use the tablespoon for small additions.
Sugar: 1 cup of granulated sugar is about 200 grams. Since sugar packs into measuring spoons fairly uniformly, tablespoon measurements for sugar are reliable.
Liquids: For milk, water, juice, and other thin liquids, tablespoon measurements are very accurate because liquids naturally level themselves. 1 cup equals 8 fluid ounces, and each tablespoon is 1/2 fluid ounce.
A common shortcut: if a recipe calls for 1/3 cup and you do not have a 1/3 cup measure, use 5 tablespoons plus 1 teaspoon. This is exact because 16/3 = 5.333, and 1/3 of a tablespoon equals 1 teaspoon.
For quick reference, many cooks keep a conversion chart on the inside of a kitchen cabinet door. The tablespoon-to-cup relationship is one of the most frequently needed conversions, alongside teaspoons-to-tablespoons and cups-to-ounces.

Frequently Asked Questions
There are exactly 16 tablespoons in 1 US cup. To convert tablespoons to cups, divide the number of tablespoons by 16. For example, 8 tablespoons equals 1/2 cup and 4 tablespoons equals 1/4 cup.
One standard US stick of butter contains 8 tablespoons, which equals 1/2 cup or 4 ounces (113 grams). Half a stick of butter is 4 tablespoons (1/4 cup). Most butter sticks have tablespoon markings printed on the wrapper for easy measuring.
3 tablespoons equals 0.1875 cups, or 3/16 of a cup. Since this is not a standard measuring cup fraction, it is more practical to simply measure 3 tablespoons directly rather than trying to use a cup measure.
1/3 cup equals 5 tablespoons plus 1 teaspoon. Since 16 divided by 3 is 5.333, and 1/3 of a tablespoon is 1 teaspoon, the precise measurement is 5 tbsp + 1 tsp. This is a common conversion needed in baking recipes.
No. A US customary cup is 236.588 ml (16 US tablespoons), while a metric cup used in Australia, New Zealand, and Canada is exactly 250 ml. The difference is about 6%, which can affect baking results. Always check which cup standard your recipe uses.
