How Do You Convert Cups to Milliliters?
Multiply the number of cups by 236.588 to get milliliters. The formula is: Milliliters = Cups x 236.588. To convert in the other direction, divide milliliters by 236.588 to get cups. This conversion uses the US customary cup, which is the standard cup measurement in American recipes and cookbooks.
Leah Novak at Rise & Shine Bakery in Pinewood Falls converts between cups and milliliters whenever she adapts international recipes. A French croissant recipe calls for 350 mL of whole milk. She divides: 350 / 236.588 = 1.48 cups, which she rounds to 1 and 1/2 cups for her measuring cup. For precise pastry work, she uses a kitchen scale instead.
Common Cup to Milliliter Conversions
The table below lists the cup measurements that appear most often in recipes, along with their milliliter equivalents. These values use the US customary cup (236.588 mL).
| Cups | Milliliters | Notes |
|---|---|---|
| 1/8 cup | 29.6 mL | 2 tablespoons |
| 1/4 cup | 59.1 mL | 4 tablespoons |
| 1/3 cup | 78.9 mL | 5 tbsp + 1 tsp |
| 1/2 cup | 118.3 mL | 8 tablespoons |
| 2/3 cup | 157.7 mL | 10 tbsp + 2 tsp |
| 3/4 cup | 177.4 mL | 12 tablespoons |
| 1 cup | 236.6 mL | Standard US cup |
| 1.5 cups | 354.9 mL | 12 fl oz |
| 2 cups | 473.2 mL | 1 US pint |
| 4 cups | 946.4 mL | 1 US quart |
When Do You Need This Conversion?
Cup to milliliter conversions are essential whenever you work with recipes, nutrition information, or products from countries that use the metric system. Here are the most common scenarios.
Adapting International Recipes
Marco Ferreira grew up with his grandmother's Italian recipes, all measured in milliliters and grams. At Marco's Kitchen in Pinewood Falls, his staff measures in cups. His grandmother's ragu calls for 700 mL of San Marzano tomatoes. Dividing by 236.588 gives 2.96 cups, so he tells his line cooks to use 3 cups. For his signature tiramisu, the precision matters more, and he measures the espresso in milliliters.
Using Metric Kitchen Equipment
Many modern kitchen tools (graduated cylinders, sous vide circulators, espresso machines) display volume in milliliters. Tom Brewer bought a pour-over coffee dripper that recommends 300 mL of water. That's 300 / 236.588 = 1.27 cups. He just fills his cup measure a quarter past the 1-cup line. His engineering background makes him appreciate the precision of metric units.
Comparing Product Sizes
Imported beverages and products often list volume in milliliters. A 330 mL can of European soda equals 330 / 236.588 = 1.39 cups, slightly less than a standard 12 fl oz (355 mL) American can. Maya Singh noticed this when comparing drink sizes for a consumer math assignment at school.
US Cup vs. Metric Cup vs. Legal Cup
Three different "cup" measurements exist, and using the wrong one can throw off a recipe. Understanding which cup a recipe means prevents mistakes, especially in baking where precision matters most.
| Cup Type | Volume (mL) | Where Used |
|---|---|---|
| US customary cup | 236.588 mL | American recipes, cookbooks |
| US legal cup | 240 mL | US nutrition labels (FDA) |
| Metric cup | 250 mL | Australia, New Zealand, Canada |
| Japanese cup | 200 mL | Japanese cooking |
| Imperial cup (historical) | 284 mL | Older British recipes |
For most cooking, the differences between these cup sizes are small enough that they will not ruin a dish. But for baking, the gap adds up. Priya Patel once tried an Australian pavlova recipe using US cups and ended up with 4 tablespoons less liquid than intended across the recipe. The result was a cracked meringue. She now converts Australian recipes to milliliters first, then to US cups using this converter.
For related conversions, try the ounces to cups converter for fluid ounce conversions, the pounds to kilograms converter for weight conversions in recipes, or the fraction calculator for working with recipe measurements like 3/4 cup or 2/3 cup.
This converter uses the US customary cup (236.588 mL). If your recipe uses metric cups (250 mL) or US legal cups (240 mL), adjust accordingly. For precise baking, a kitchen scale measuring in grams is more accurate than volume conversions.
