How to Convert Cups to Milliliters
This converter changes U.S. customary cups into milliliters using the standard relationship of 1 U.S. cup = 236.5882365 mL. Enter the number of cups and run the conversion to get the equivalent metric volume.
Practical Cups to Milliliters Example
If a recipe calls for 1.5 U.S. cups, multiply 1.5 by 236.5882365. The result is approximately 354.88 mL. This is useful when adapting U.S. recipes to metric measuring jugs or scales with liquid markings.
Factors That Affect the Result
The definition of a cup is important. This tool uses the U.S. customary cup, which differs from the 250 mL metric cup used in some countries. Measurement accuracy also depends on how precisely the source volume is filled and read.
Frequently Asked Questions
How many milliliters are in one U.S. cup?
One U.S. customary cup equals approximately 236.59 mL.
Is a metric cup the same as a U.S. cup?
No. A metric cup is commonly defined as 250 mL, while a U.S. customary cup is about 236.59 mL.
Can I use this for recipe conversions?
Yes. It is suitable for liquid and volume-based recipe measurements that use U.S. customary cups.
Methodology and Practical Limits
Milliliters per cup vary by standard: metric, US legal and US customary cups are not identical. Choose the recipe’s cup convention before converting so ingredient volume is not systematically over- or understated.
