What is a Cup (US) and a Milliliter?
The US customary cup is a unit of volume used in the United States for cooking and serving sizes. It is defined as exactly 8 US customary fluid ounces. This equates to approximately 236.59 milliliters (mL).
The milliliter (symbol mL or ml) is a metric unit of volume equal to one-thousandth of a liter (1/1000 L). It is also equivalent to exactly one cubic centimeter (1 cm³). The milliliter is widely used in scientific measurements, medicine, and cooking.
Note: The Cup (US) is part of the imperial/US customary system, primarily used in the US, UK, and Canada for everyday measurements. The Milliliter belongs to the metric (SI) system.
History of the Cup (US) and Milliliter
The concept of a 'cup' as a measurement unit evolved informally over centuries. The US customary cup was standardized based on the US gallon, which itself derived from the older English wine gallon. Unlike the metric cup (250 mL) or the imperial cup (approx. 284 mL), the US cup was legally defined in terms of the gallon (1 US gallon = 16 US cups).
The milliliter derives directly from the liter, established in France in 1795. As the metric system gained international acceptance, prefixes like 'milli-' (meaning one-thousandth) were applied to base units to create smaller or larger units. The equivalence 1 mL = 1 cm³ is a fundamental relationship in the metric system.

Frequently Asked Questions
Questions About Cup (US) (cup)
How many fluid ounces are in a US cup?
There are exactly 8 US customary fluid ounces (fl oz) in 1 US cup.
How many milliliters are in a US cup?
One US cup is equivalent to approximately 236.59 milliliters (mL).
Is a US cup the same as a metric cup or an imperial cup?
No. A US cup (~236.59 mL) is smaller than both a metric cup (250 mL) used in many Commonwealth countries and an imperial cup (~284.13 mL) which is less commonly used today but part of the UK imperial system.
About Milliliter (mL)
Is a milliliter the same as a cubic centimeter (cc)?
Yes, 1 milliliter (mL) is exactly equal to 1 cubic centimeter (cm³ or cc). The terms are often used interchangeably, especially in medical and automotive contexts (e.g., engine displacement often uses cc).
How many milliliters are in a liter?
There are 1,000 milliliters (mL) in 1 liter (L).
Is mL or ml the correct symbol?
Both are technically correct and commonly understood. Similar to the liter (L/l), the capitalized version 'mL' is often preferred in publishing and medicine to avoid confusion between 'l' and the number '1'.
