Conversion Example
- Convert 24 tablespoons to cups:
- Divide 24 by 16: 24 ÷ 16 = 1.5 cups.
- This means 24 tablespoons equals one and a half cups.
- Convert 5 tablespoons to cups:
- Divide 5 by 16: 5 ÷ 16 = 0.3125 cups.
- So, 5 tablespoons is just under one-third cup.
- Convert 40 tablespoons to cups:
- Divide 40 by 16: 40 ÷ 16 = 2.5 cups.

Conversion Definitions
tbsp (Tablespoon): A tablespoon is a unit of volume commonly used in cooking to measure liquids and dry ingredients. One tablespoon is equal to 3 teaspoons or 15 milliliters in the metric system. In the US customary system, it is part of kitchen measurement and helps in portioning ingredients precisely.
Cups: A cup is a volume unit used in cooking and food preparation, primarily in the US customary system. One cup equals 16 tablespoons or 8 fluid ounces, which is approximately 237 milliliters. Cups are used to measure both liquid and dry ingredients, making it a versatile cooking measure.
Conversion FAQs
Why does dividing tablespoons by 16 give cups?
Since 1 cup contains exactly 16 tablespoons, dividing the number of tablespoons by 16 converts the volume into cups. This is a direct proportional conversion because the tablespoon is a smaller unit nested within the cup. So, the division calculates how many whole or fractional cups fit into the tablespoons.
Can I convert tablespoons to cups without a calculator?
Yes, you can approximate by remembering that 16 tablespoons equal 1 cup. For example, 8 tablespoons equals ½ cup, 4 tablespoons equals ¼ cup, and so on. For values like 12.5 tablespoons, you can think of it as 12 tablespoons plus ½ tablespoon, which is ¾ cup plus a small amount.
What happens when converting negative tablespoons to cups?
Negative tablespoons represent a subtraction or reduction in volume, possibly in recipe adjustments. The conversion still works the same way by dividing by 16, but the result will be a negative cup value indicating less than zero volume, useful for calculations involving deficits or corrections.
Is the tablespoon volume the same worldwide?
No, tablespoon size can vary slightly by country. The US tablespoon is 14.79 ml, the UK tablespoon historically has been 17.76 ml, and Australia uses 20 ml. This affects conversions if you use non-US tablespoons, but in US cooking, 1 tbsp = 1/16 cup consistently.
Why are cups used instead of tablespoons for some recipes?
Cups provide a larger measurement unit, so for bigger quantities, cups simplify the measurement process. Using cups reduces counting many tablespoons and improves ease of measuring, especially in recipes requiring larger volumes of ingredients.
