Cups to ML Converter

Step 1: Enter the value you want to convert in the input field.

Step 2: Click Calculate. The result shows the converted value in milliliters. The breakdown shows the input value and the conversion factor used.

US recipes use cups while most international recipes use milliliters. This converter bridges the gap for home cooks following recipes from different countries. The US cup (236.59 mL) differs from the metric cup (250 mL) and the Japanese cup (200 mL).

Common uses for this conversion: recipe conversion, international cooking, measuring liquids, scaling recipes up or down.

Professional bakers and chefs increasingly prefer metric measurements because they are more precise and scale more easily. A recipe calling for 237 mL of water is more exact than "1 cup" because cup measurements depend on how the measuring cup is filled. For critical recipes (bread, pastry, candy), metric weights in grams are even more reliable than volume in mL.

milliliters = US cups × 236.588

Multiply the value in US cups by 236.588 to get the equivalent in milliliters.

To convert back: US cups = milliliters × 0.00423

Divide the value in milliliters by 236.588 (or multiply by 0.00423) to convert back.

Example 1: Recipe Conversion
Enter 1.5. Result: 354.88 mL — for following a metric recipe. 1.5 cups × 236.59 = 354.88 mL.

Example 2: Baby Formula
Enter 0.5. Result: 118.29 mL — a half-cup serving. 0.5 × 236.59 = 118.29 mL.

Example 3: Large Batch
Enter 4. Result: 946.35 mL — close to 1 liter (1,000 mL). 4 cups is almost exactly 1 quart, which is close to 1 liter.

Memorize a few key values. Know that 1/8 cup = 29.6 mL and 2/3 cup = 157.7 mL. These reference points help you estimate without calculating.

Double-check by converting back. Multiply your result by 0.00423 to verify it returns to the original value. This catches data entry errors.

Use the conversion factor for bulk calculations. If you need to convert many values, multiply each by 236.588. The factor is exact and does not change.
