To convert tablespoons to cups, divide the number of tablespoons by 16. Because 1 standard US cup contains exactly 16 tablespoons, this formula works universally for liquids, dry ingredients, butter, and oils.

Quick facts
- Core formula
- Cups = tablespoons divided by 16.
- Cup standard
- 1 US customary cup equals 16 tablespoons (236.6 ml).
- Half cup
- 8 tablespoons equals exactly 1/2 cup (1 stick of butter).
- Quarter cup
- 4 tablespoons equals exactly 1/4 cup (1/2 stick of butter).
- Australian warning
- Australian tablespoons are 20 ml (4 tsp), unlike 15 ml US/UK spoons.
The Golden Tablespoon to Cup Formula
Converting tablespoons to cups is straightforward because both units measure volume. Unlike grams-to-cups conversions that depend on ingredient density, the ratio of tablespoons to cups is constant: exactly 16 tablespoons per US cup.
Use the formula: cups = tablespoons ÷ 16. For example, 12 tablespoons divided by 16 equals 0.75 or 3/4 cup. 4 tablespoons divided by 16 equals 0.25 or 1/4 cup.
When scaling recipes up or down in the kitchen, remembering simple fractions saves time: 8 tablespoons is always 1/2 cup, 4 tablespoons is 1/4 cup, and 2 tablespoons is 1/8 cup (or 1 fluid ounce).

| 3 tbsp | 3/16 cup (0.1875 c) | 1.5 fl oz | 44.4 ml |
| 4 tbsp | 1/4 cup (0.25 c) | 2.0 fl oz | 59.1 ml |

| 12 tbsp | 3/4 cup (0.75 c) | 6.0 fl oz | 177.4 ml |
| 14 tbsp | 7/8 cup (0.875 c) | 7.0 fl oz | 207.0 ml |

Measuring Butter: Sticks, Tablespoons, and Cups
In American baking, butter is commonly sold in 4-ounce sticks wrapped with tablespoon guide marks. One standard stick of butter equals 8 tablespoons (1/2 cup), and two sticks equal 16 tablespoons (1 full cup).
If a recipe calls for 6 tablespoons of butter, slice along the wrapper marks, which equals 3/8 of a cup (approximately 85 grams or 3 ounces).
When working with European butter blocks (which are usually sold in 250g or 500g packages without tablespoon marks), weigh the butter with a digital kitchen scale: 1 tablespoon of butter weighs approximately 14.2 grams.
International Tablespoon Differences: US vs UK vs Australia
Not all tablespoons are created equal. While a US customary tablespoon holds 14.8 ml and a UK/Commonwealth metric tablespoon holds 15.0 ml, Australia legally defines a tablespoon as 20.0 millilitres (equal to 4 teaspoons instead of 3).
If you are following an Australian baking recipe and use an American or British tablespoon, your baked goods will receive 25% less volume than intended. Always check the origin country of your recipe.

Frequently asked questions
How many tablespoons are in 1 standard US cup?
There are exactly 16 standard US tablespoons in 1 US customary cup (equivalent to 8 fluid ounces or approximately 236.6 millilitres).
How many tablespoons is 1/2 cup, 1/3 cup, and 1/4 cup?
1/2 cup equals 8 tablespoons; 1/3 cup equals 5 tablespoons plus 1 teaspoon (5.33 tbsp); 1/4 cup equals exactly 4 tablespoons.
How many tablespoons are in a stick of butter?
In the United States, 1 standard stick of butter equals 8 tablespoons (1/2 cup, 4 ounces, or approximately 113.4 grams).
Why is an Australian tablespoon different from a US or UK tablespoon?
An Australian tablespoon is legally defined as 20 millilitres (4 teaspoons), whereas a US tablespoon is 14.8 ml and a UK/Canadian metric tablespoon is 15 ml (3 teaspoons). Using an Australian tablespoon in an American recipe adds 33% extra volume.
What is the difference between a liquid tablespoon and a dry tablespoon?
A standard measuring tablespoon measures liquid and dry volume identically (approximately 14.8 ml). However, dry ingredients must be levelled flat with a knife, whereas liquids form a natural surface meniscus.
How do I measure flour accurately using tablespoons?
Fluff your flour with a fork, spoon it gently into the measuring spoon without pressing, and sweep the excess level with the straight back of a butter knife. Never scoop directly from a packed bag.
How many tablespoons are in 1/8 of a cup?
1/8 cup equals exactly 2 tablespoons (equivalent to 1 fluid ounce or 6 teaspoons).
Can I use a regular eating soup spoon as a measuring tablespoon?
No. Everyday dining flatware varies wildly between 8 ml and 18 ml and is designed for eating comfort rather than volumetric accuracy. Always use calibrated measuring spoons for baking.
How many teaspoons are in 1 tablespoon?
There are exactly 3 teaspoons in 1 tablespoon in the US, UK, and Canadian measurement systems (and 4 teaspoons in Australia).
What is the millilitre (ml) equivalent of 1 US tablespoon?
1 US customary tablespoon equals exactly 14.7868 millilitres (commonly rounded to 15 ml in commercial recipe books).
The takeaway
