Cups (US) to Milliliters (cup to mL)

What Is Cups (US) TO Milliliters?

To convert US cups to milliliters, multiply the cup value by 236.588. One US cup equals approximately 236.59 mL. For example, 2 cups equals about 473.18 mL. This conversion is indispensable in baking and cooking, where American recipes use cups as the primary volume measurement for both liquid and dry ingredients. International bakers following American recipes need precise milliliter equivalents to achieve consistent results — baking is particularly sensitive to measurement accuracy, and using the wrong cup size can ruin a recipe. Note that the US legal cup (used on nutrition labels) is exactly 240 mL, slightly different from the US customary cup of 236.588 mL. The metric cup used in Australia and New Zealand is exactly 250 mL. Japanese recipes use a cup of 200 mL. These variations mean that simply knowing "cups to milliliters" is not enough — you must know which cup standard the recipe uses. For most American home cooking recipes, the 236.588 mL US customary cup is correct. Professional pastry chefs often prefer weighing ingredients in grams for better precision, but volume-based cup measurements remain the standard in American home kitchens and cookbooks.

Formula

To convert US customary cups to milliliters, multiply by 236.588. This factor is derived from the fact that 1 US cup = 8 US fluid ounces, and 1 US fluid ounce = 29.5735 mL, so 8 x 29.5735 = 236.588 mL. Worked example: 1.5 cups x 236.588 = 354.88 mL. For quick mental math, multiply cups by 237 or simply by 240 (the US legal cup value) for a close approximation. Example: 3 cups x 240 = 720 mL (actual: 709.76 mL).

Best For:

• Baking American recipes with metric measuring equipment
• Scaling recipes that mix cup and milliliter measurements
• Preparing infant formula or nutritional drinks with precise milliliter amounts from cup-based instructions
• Converting American cocktail recipes for bars using metric jiggers and graduated cylinders
• Adapting US cooking class materials for international culinary students
