What is the Cups to Milliliters Converter?
This tool converts a volume measured in US customary cups into milliliters (mL), the standard metric unit of volume used in most kitchens worldwide. It uses the US legal/customary cup, which equals 236.588 mL. This is especially handy when following American recipes with a metric measuring jug, or vice versa.
How to use it
Enter the number of cups you want to convert and read the result in milliliters. You can use whole numbers or decimals — for example, 0.5 cups or 1.75 cups. The converter handles fractional cup amounts common in baking.
The formula explained
The conversion is a simple multiplication:
$$\text{mL} = \text{Cups (US)} \times 236.588$$
One US cup is defined as 236.5882365 mL, rounded here to 236.588 mL for everyday accuracy. To go the other way, divide milliliters by 236.588 to get cups.
Worked example
Suppose a recipe calls for 2.5 cups of milk. Multiply: $$2.5 \times 236.588 = 591.47 \text{ mL}$$ So you would measure about 591 mL of milk.
