🥤 Cups to mL Converter
Convert cups to milliliters and vice versa instantly.
If you have ever tried to follow a recipe that uses cups when your measuring jug only shows milliliters, you know the frustration. This cups to milliliters converter bridges the gap between American and metric measuring systems, giving you an accurate conversion in a single click. Whether you are baking a layered cake, mixing a cocktail, or portioning out baby formula, knowing the exact milliliter equivalent of a cup measurement takes the guesswork out of the kitchen.
For example, your friend shares a legendary banana bread recipe that calls for 2½ cups of flour. Your kitchen scale and measuring jug are metric — what do you do? Simply enter 2.5 in the converter, select “Cups” as your source and “Milliliters” as your target, and you will see the result instantly. At the standard US conversion rate of 1 cup = 236.588 mL, 2½ cups equals about 591.47 mL. Easy.
The conversion is based on the US customary cup, which is the standard in American recipes. This is slightly different from the metric cup (250 mL) used in some parts of the world and the imperial cup (284 mL) used in older British cookbooks. By using this tool, you ensure your measurements are consistent with the vast majority of modern English-language recipes.
Keep this converter bookmarked for all your cooking and baking needs. It is especially handy when you are using a European cookbook with metric measurements but prefer working in cups, or when you need to quickly adjust a recipe for a different number of servings.
Frequently Asked Questions
How many milliliters are in one cup?
One US cup equals exactly 236.588 mL. This is the standard used in American recipes and is the conversion this tool uses. For most cooking purposes, you can round this to 237 mL or even 240 mL without significantly affecting your results.
Is a US cup the same as a metric cup?
No — a US cup is 236.588 mL, while a metric cup (used in Australia, New Zealand, and parts of Europe) is 250 mL. Older British recipes sometimes use an imperial cup of 284 mL. Always check which standard your recipe follows before converting.
How do I convert ¾ cup to milliliters?
Simply enter 0.75 in the converter, select "Cups" as the source and "Milliliters" as the target. The result will be 177.44 mL. This is a very common baking measurement — ¾ cup of milk, water, or oil shows up in countless recipes.
Can I use this converter for liquid and dry ingredients?
This converter works for volume measurements, so it is accurate for liquids like water, milk, and oil. For dry ingredients like flour or sugar, volume-to-volume conversion (cups to mL) is still the same, but keep in mind that the weight of a cup of dry ingredients varies — 1 cup of flour weighs much less than 1 cup of sugar.
