Exact conversion relationship
One US customary cup is 236.5882365 mL. Other cup standards define different volumes, so the selected standard matters.
Where this is useful
Millilitre-to-cup conversion helps adapt metric recipes, drink volumes and package measurements to cup-based instructions.
Understanding the result
US customary, US legal, metric, imperial and Japanese cups are different volume measures. The results compare the selected definition with the alternatives.
Important measurement note
Millilitres and cups both measure volume. A separate ingredient density is still required before converting the result to grams or ounces by weight.
A cup measures volume, not mass. Converting to grams requires the ingredient’s density.
Precision and rounding
The calculator keeps full precision internally and rounds only displayed values. Match the chosen precision to the accuracy of the original measurement.
Batch conversion for lists
Paste a short list to create a clean two-column result table for recipes, specifications, logs or comparisons.
