Cups and milliliters are the primary volume measurement units used across domestic baking recipes, professional culinary kitchens, nutrition labeling, cocktail mixology, and coffee brewing. While the US customary cup is standard in North American cookbooks, international recipes from Europe, Australia, New Zealand, Canada, and Asia specify volume in milliliters (mL) or metric cups.

Our free online Cups to Ml Converter provides instant, high-precision volume conversions in both directions:

  • US Customary Cups to Milliliters: Multiply US cups by 236.5882365 (exact customary standard).
  • US Legal Cups (FDA Nutrition Labels) to Milliliters: Multiply cups by 240 (exact US FDA standard).
  • Metric Cups (UK / Australia / NZ) to Milliliters: Multiply metric cups by 250 (exact metric standard).
  • Milliliters to US Customary Cups: Divide mL by 236.5882365 (or multiply by 0.00422675).

International Cup Sizes Comparison Table

Because different countries define the “cup” unit differently, converting cups to milliliters requires selecting the correct cup standard:

History & Culinary Standards: Fannie Farmer vs. Metric System

Fannie Farmer and the Standardization of the Cooking Cup (1896)

Before the late 19th century, recipe ingredients were described using informal household teacups, coffee cups, or wine glasses, leading to unpredictable baking results. In 1896, American culinary pioneer Fannie Farmer published The Boston Cooking-School Cook Book, formalizing standardized level measuring cups and spoons across North America. The US customary cup was set to 1/16th of a US gallon (8 fluid ounces = 236.5882365 mL).

The Metric Cup (250 mL) and US Legal Cup (240 mL)

When Commonwealth nations (UK, Australia, New Zealand, Canada) metricated their kitchens, they standardized the metric cup as exactly 250 milliliters (1/4th of a liter). Meanwhile, the US Food and Drug Administration (FDA) created the US legal cup of exactly 240 mL to simplify nutrition serving sizes on food package labels.
