Tablespoons to Cups Conversion

How to use this calculator

Enter the number of tablespoons. Use whole numbers or decimals. Select your tablespoon standard (US, Australian, UK, or Metric). Press Calculate to see cups, teaspoons, millilitres, and fluid ounces.

The tablespoon-to-cup relationship

The US kitchen measurement system is built on exact ratios. The foundational relationship:

Dividing this by common fractions:

Tablespoons	Cups	Teaspoons	mL
1 tbsp	1/16 cup	3 tsp	14.79 mL
2 tbsp	1/8 cup	6 tsp	29.57 mL
4 tbsp	1/4 cup	12 tsp	59.15 mL
5 tbsp + 1 tsp	1/3 cup	16 tsp	78.86 mL
8 tbsp	1/2 cup	24 tsp	118.29 mL
10 tbsp + 2 tsp	2/3 cup	32 tsp	157.72 mL
12 tbsp	3/4 cup	36 tsp	177.44 mL
16 tbsp	1 cup	48 tsp	236.59 mL
32 tbsp	2 cups (1 pint)	96 tsp	473.18 mL

The most important to memorise: 16 tablespoons = 1 cup, and the common fractions: 4, 8, and 12 tablespoons for 1/4, 1/2, and 3/4 cup.

Tablespoon standards by country

One tablespoon does not mean the same volume in every country. This becomes important when following international recipes.

Country	Tablespoon Volume	Notes
United States	14.787 mL	3 teaspoons (4.929 mL each)
Australia / New Zealand	20 mL	4 teaspoons (5 mL each)
United Kingdom	~17.76 mL	Historically variable; metric versions use 15 mL
Metric (international)	15 mL	3 teaspoons of 5 mL each
Canada	15 mL	Follows metric standard

The Australian difference is the largest. An Australian recipe calling for 3 tablespoons uses 60 mL (3 x 20 mL), while the same recipe made with US tablespoons delivers only 44.4 mL (3 x 14.787 mL). This 35% difference can significantly change a dish.

When in doubt: Look at the country of origin for the recipe. If it is from an Australian cookbook or website, use the 20 mL tablespoon setting. If from a US recipe (most English-language online recipes), use the US 14.787 mL setting.

Why 1/3 cup is the “awkward” fraction

Every common cup fraction converts cleanly to tablespoons except 1/3:

• 1/4 cup = 4 tablespoons (clean)
• 1/2 cup = 8 tablespoons (clean)
• 3/4 cup = 12 tablespoons (clean)
• 1/3 cup = 5.333 tablespoons = 5 tablespoons + 1 teaspoon (awkward)
• 2/3 cup = 10.667 tablespoons = 10 tablespoons + 2 teaspoons (awkward)

The reason is that 1/3 of 16 is not a whole number. The workaround used in recipes: “5 tablespoons + 1 teaspoon” because 1/3 tablespoon = 1 teaspoon (since 1 tablespoon = 3 teaspoons).

For baking, if you do not have a 1/3 cup measuring tool, measure out 5 tablespoons and then add 1 level teaspoon to get an accurate 1/3 cup. Alternatively, use a 79 mL measure on a liquid measuring jug.

Tablespoons in common recipes

Understanding where tablespoon-to-cup conversions appear most often:

Butter: US recipes frequently call for butter in tablespoons. 1 stick of butter = 8 tablespoons = 1/2 cup = 113.4 g. A recipe calling for “4 tablespoons of butter” wants 1/4 cup = half a stick.

Oil: Salad dressing recipes often use tablespoons. 4 tablespoons of olive oil = 1/4 cup = 59 mL. A standard vinaigrette ratio of 3:1 oil to vinegar often uses “6 tablespoons oil + 2 tablespoons vinegar” — converting to cups: 3/8 cup oil + 1/8 cup vinegar.

Honey and syrup: Small quantities of sweeteners are measured in tablespoons. 2 tablespoons of honey = 1/8 cup = 29.6 mL.

Spice pastes and condiments: Recipes using tahini, peanut butter, or miso often call for 2 to 6 tablespoons. 6 tablespoons = 3/8 cup.

Liquids (milk, cream, stock): When a recipe calls for “a cup plus 2 tablespoons,” the total is 18 tablespoons = 266 mL = about 1.125 cups.

Tablespoon to cup conversion for doubled and halved recipes

Scaling recipes requires converting back and forth between tablespoons and cups:

Doubling a recipe:

• 2 tablespoons x 2 = 4 tablespoons = 1/4 cup
• 3 tablespoons x 2 = 6 tablespoons = 3/8 cup
• 8 tablespoons x 2 = 16 tablespoons = 1 cup
• 12 tablespoons x 2 = 24 tablespoons = 1.5 cups

Halving a recipe:

• 1 cup / 2 = 8 tablespoons = 1/2 cup
• 3/4 cup / 2 = 6 tablespoons = 3/8 cup
• 1/3 cup / 2 = 2 tablespoons + 2 teaspoons
• 1/4 cup / 2 = 2 tablespoons

The most difficult halving is any fraction involving 1/3 because halving 5 tbsp + 1 tsp gives 2.5 tbsp + 0.5 tsp, which requires either a 1/2-tablespoon measure or careful teaspoon counting (2 tbsp + 1.5 tsp = half of 1/3 cup).

Tablespoons to cups for dry ingredients

When measuring dry ingredients by tablespoon and converting to cups, keep in mind that weight-to-volume relationships vary by ingredient.

Ingredient	1/4 cup (4 tbsp) in grams	1 cup (16 tbsp) in grams
All-purpose flour	30 g	120 g
White sugar	50 g	200 g
Brown sugar (packed)	55 g	220 g
Powdered sugar	30 g	120 g
Butter	56.7 g	227 g
Cocoa powder	21.6 g	86.5 g
Salt (table)	68.3 g	273 g
Baking powder	57.5 g	230 g

For any conversion from tablespoons to cups, the volume relationship is always 16 tbsp = 1 cup. The grams shown above are the mass equivalents using standard density values.
