How to Convert Cups to Milliliters
To convert cups to milliliters, multiply the volume by the following conversion ratio: 236.5882365 milliliters/cup.
Since one cup is equal to 236.5882365 milliliters, you can use this simple formula to convert:
The volume in milliliters is equal to the volume in cups multiplied by 236.5882365.
For example, here's how to convert 2 cups to milliliters using the formula above.
How Many Milliliters Are in a Cup?
There are 236.5882365 milliliters in a cup, which is why we use this value in the formula above.
Our cup to milliliter calculator automatically converts your volume measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
Cups and milliliters are both units used to measure volume. Keep reading to learn more about each unit.
What Is a Cup?
A cup is a unit of volume equal to 0.2365882 liters (L), the base unit for volume. Equal to 8 US fluid ounces or 16 US tablespoons (236.59 mL). [1]
The cup is classified as a US customary unit of volume. Cups can be abbreviated as cup; for example, 1 cup can be written as 1 cup.
When working with cups (cup) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, cups (cup) are widely used across standard volume applications within US customary workflows, engineering documentation, and technical data sheets.
What Is a Milliliter?
A milliliter is a unit of volume equal to 1/1,000 of a liter (0.001 L). One-thousandth of a liter, identical to 1 cubic centimeter (cc). [2]
The milliliter is classified as a metric and SI-compatible unit of volume. Milliliters can be abbreviated as mL; for example, 1 milliliter can be written as 1 mL.
In the metric system, "milli" is the standard SI prefix for thousandths, or 10⁻³. This makes the milliliter (mL) a convenient decimal multiple of the liter (L).
In practice, milliliters (mL) are widely used across fine-tolerance laboratory, analytical, and micro-scale volume measurements within SI metric workflows, engineering documentation, and technical data sheets.
When converting volume between cups (cup) and milliliters (mL), keep full floating-point precision (1 cup = 236.5882365 mL; 1 mL = 0.0042268 cup) during intermediate calculations and round only the final milliliter figure to match your instrument tolerance.
