Milliliters and cups are the most frequently used volume units in culinary recipes, liquid measurements, nutritional serving sizes, and kitchen baking worldwide. While the millimeter (mL) is the standard decimal metric subunit (1/1,000th of a liter) used in European, Asian, and scientific recipes, the cup is the standard volume unit used across the United States, Canada, the United Kingdom, Australia, and New Zealand.
Our free online Ml to Cups Converter provides instant, accurate volume conversions in both directions:
- Milliliters to US Customary Cups: Divide mL by
236.5882365(or multiply by0.00422675). - Milliliters to Metric Cups: Divide mL by
250(exact 250 mL standard). - Milliliters to US Legal Cups: Divide mL by
240(FDA nutrition label standard).
Comparing International Cup Definitions
Different countries and organizations use slightly different definitions for a “cup.” Knowing which cup your recipe uses prevents baking errors:
| Cup Definition | Region / Primary Usage | Exact Volume in mL | Ml to Cups Formula |
|---|---|---|---|
| US Customary Cup | United States home baking & recipes | 236.5882365 mL (8 US fl oz) |
Cups = mL ÷ 236.588 |
| US Legal Cup | US FDA Nutrition Facts labels | 240.0000000 mL (exact) |
Cups = mL ÷ 240 |
| Metric Cup | UK, Australia, NZ, Commonwealth, Canada | 250.0000000 mL (exact) |
Cups = mL ÷ 250 |
| Imperial Cup | Historical British recipes | 284.1306250 mL (10 UK fl oz) |
Cups = mL ÷ 284.131 |
Step-by-Step Calculation Example
To convert 15 mL to US customary cups:
15 mL ÷ 236.5882365 = 0.063401 US cups (or 1 US tablespoon)
Thus, 15 mL is equal to approximately 0.063 US cups.

History & Culinary Standards: Millimeter vs. Cup
The Origin of the Milliliter (mL)
The milliliter is a submultiple of the liter in the International System of Units (SI). Derived from the French litre (originally litron, an ancient French measurement for grain and wine), 1 mL equals 1 cubic centimeter (1 cm³ / 1 cc) or 1/1,000th of a liter. Today, milliliters are the standard volume unit for liquids across science, pharmacy, and international cooking.
The Origin of the Customary Cup
Historically, cooks used ordinary drinking cups to measure ingredients. In 1896, Fannie Farmer (principal of the Boston Cooking School) standardized culinary measurements in her famous cookbook, establishing the cup as a precise unit of 8 fluid ounces. In 1959, international standards locked 1 US customary fluid ounce to 29.5735 mL, making 1 US customary cup equal to 236.5882365 mL.
