- Rounded to 4 decimal places: 1.0646 liters
Conversion Example
- Convert 3 cups to liters:
- Take the number 3.
- Multiply by 0.236588: 3 × 0.236588 = 0.709764 liters.
- The result is about 0.7098 liters after rounding.
- Convert 7.25 cups to liters:
- Start with 7.25 cups.
- Calculate 7.25 × 0.236588 = 1.715753 liters.
- Rounded value is 1.7158 liters.
- Convert 0.5 cups to liters:
- Multiply 0.5 by 0.236588.
- Result: 0.118294 liters.
- This shows half a cup is less than a quarter liter.
- Convert 10 cups to liters:
- Multiply 10 × 0.236588 = 2.36588 liters.
- This means 10 cups is a little over 2 liters.

Conversion Definitions
Cups: A cup is a unit of volume used in cooking and serving sizes, mostly common in the US and Canada. One US cup equals 8 fluid ounces, or approximately 236.588 milliliters. It is not part of the metric system but often used for measuring liquids and dry ingredients in recipes.
Liters: A liter is a metric system unit of volume measuring fluids or substances, equal to 1,000 cubic centimeters or one cubic decimeter. It is widely used worldwide for liquid measurements in everyday and scientific contexts, with precise definitions based on the International System of Units.
Conversion FAQs
Can I use the same conversion factor for UK cups?
No, UK cups differ slightly from US cups. A UK cup is larger (about 284 ml), so using the US conversion factor (0.236588) for UK cups will give inaccurate results. You must use the UK cup equivalent, which is approximately 0.284 liters for more precise conversions.
Why does the conversion factor have so many decimal places?
The conversion factor 0.236588 liters per cup is precise to ensure accuracy in measurements. Cooking or scientific calculations require exact values to avoid errors, especially in recipes or chemical mixtures where small volume changes can affect results.
How to convert cups to liters without a calculator?
You can approximate by knowing 1 cup is about 0.24 liters. Multiply the number of cups by 0.24 for a rough estimate. For example, 4.5 cups × 0.24 ≈ 1.08 liters, which is close to the exact value but less precise.
Is the conversion different for dry and liquid cups?
The volume conversion remains the same between cups and liters, but dry ingredients measured in cups can vary in weight due to density. So while volume conversion is constant, the actual mass or weight depends on the ingredient being measured.
Are there any common mistakes converting cups to liters?
Many confuse US and metric cups or forget to use the correct conversion factor. Also, neglecting to consider rounding errors or using volume for weight measurements can cause mistakes. Always check the type of cup and the purpose of conversion for correct results.
