Cups to Milliliters: Your Ultimate Global Kitchen Conversion Guide
Have you ever been halfway through a recipe only to hit a wall when it calls for 2 cups of broth, but your only measuring jug shows milliliters? Or perhaps you’re following an amazing baking tutorial from overseas, and the ingredients list is a baffling mix of cups, grams, and milliliters. You’re not alone. The confusion between volumetric cups and the metric system’s milliliters is one of the most common kitchen dilemmas worldwide. This isn’t just about following a recipe—it’s about achieving culinary precision, ensuring your cakes rise perfectly, your sauces thicken correctly, and your meals taste exactly as intended.

This comprehensive guide will demystify the conversion, providing you with the expertise, tools, and confidence to navigate any recipe with ease, turning a potential cooking disaster into a guaranteed success.
Why Accurate Cups to Milliliters Measurement Matters
Before diving into numbers, let’s understand the stakes. In cooking, especially in baking, precision is non-negotiable. Baking is a science where chemical reactions depend on exact ratios. A slight miscalculation in liquid volume can lead to a dense cake, runny batter, or broken emulsion. For liquids like water, milk, or oil, volume conversion is direct. For dry ingredients like flour or sugar, a “cup” measurement refers to volume, not weight, which is why weight (grams) is often more accurate. However, for liquids and many simple recipes, mastering the cup to milliliter conversion is essential for consistency and reproducibility.
The Core Challenge: There Is No Single Cup
The most critical fact to grasp is that a “cup” is not a universal standard. Its volume varies by country. This is the root of most conversion errors.
The US Customary Cup: The most commonly referenced cup in online recipes. 1 US cup = 236.588 mL, which is typically rounded to 237 mL or 240 mL for convenience.
The US Legal Cup: Used for nutritional labeling. 1 US legal cup = 240 mL exactly.
The Metric Cup: Used in countries like the UK, Canada, Australia, and New Zealand. 1 metric cup = 250 mL exactly. This is a clean, easy conversion.
The Imperial Cup (UK): An older, now less-common unit. 1 Imperial cup ≈ 284.131 mL.
For the purposes of this guide and the vast majority of modern recipes, we will focus on the US Customary Cup (≈240 mL) and the Metric Cup (250 mL). Always check a recipe’s origin if possible.
The Definitive Cups to Milliliters Table & Conversion Formula
Let’s get to the practical data. Here is a comprehensive conversion chart for the US Cup (using 240 mL for simplicity) and the Metric Cup.

The Cups to ML Formula Explained
The math behind the conversion is straightforward.
For US Cups: mL = Cups × 240
For Metric Cups: mL = Cups × 250
Example: How many milliliters is 2.5 US cups?
Calculation: 2.5 cups × 240 mL/cup = 600 mL.
Step-by-Step Guide: How to Convert Cups to Milliliters Accurately
Identify the Cup Type: This is the most crucial step. Look for clues in the recipe. Does it use “grams” for other ingredients (suggesting metric)? Is the author/blog from the US, UK, or Australia? If unsure, the US standard (240 mL) is a safe default for much of the internet.
Choose Your Tool: Decide if you’ll use mental math, a cups to ml calculator, a conversion chart, or physically measure.
Perform the Conversion: Use the formula or reference the chart above. For fractions of a cup, use the provided values.
Measure with the Right Equipment: If converting to measure, use a clear liquid measuring jug with mL markings. Place it on a level surface and view it at eye level for accuracy.
Double-Check for Critical Recipes: For baking, yeast breads, or delicate sauces, verify your conversion. A quick online search for “convert cups to milliliters” can serve as a reliable backup.
Cups vs Milliliters: A Global Perspective on Kitchen Standards
The divide between cups and milliliters is more than just units; it reflects different culinary traditions.
North America (US & Canada): Heavily reliant on volume measurements (cups, tablespoons, teaspoons). The US cup to milliliters conversion is indispensable here.
United Kingdom & Ireland: Officially metric, but older cookbooks may use Imperial cups or ounces. Modern recipes use grams and milliliters, with the occasional “cup” meaning a metric 250ml cup.
Australia, New Zealand, South Africa: Firmly metric. A “cup” in an Australian recipe is always 250 mL. Their tablespoon is 20 mL, another key difference.
Europe, Asia, and most of the world: Use the metric system exclusively (grams and milliliters). Recipes from these regions will rarely use “cups,” making a cups to milliliters conversion tool vital for those using American recipes.
Pro Tips for Cups to Milliliters Cooking and Baking
Invest in a Digital Scale: For ultimate accuracy, especially with dry ingredients, weight in grams is king. A cup of flour can vary by 20% based on how you scoop it. 1 cup of all-purpose flour is approximately 120-125 grams.
Use Standardized Measuring Cups: Use proper nesting dry measuring cups (for flour, sugar) and clear liquid measuring cups (for water, milk). Don’t interchange them.
Liquid vs. Dry: The cups to milliliters liquid conversion is exact for water, milk, oil, etc. For dry ingredients, converting “cups” to mL measures volume, not weight, which can be less precise.
Create Your Own Cheat Sheet: Print a cups in milliliters chart and stick it inside your kitchen cabinet for quick reference.
Essential Cups to Milliliters Conversion for Recipes: Common Equivalents
Memorize these key cups to milliliters for recipes to speed up your cooking:
1/4 cup = 60 mL (US) / 62.5 mL (Metric)
1/3 cup = 80 mL (US) / ~83 mL (Metric)

One US customary cup is equal to 236.588 milliliters, but for practical kitchen use, it is rounded to 240 milliliters.
2. Is 1 cup equal to 250 ml or 240 ml?
It depends. A metric cup (used in the UK, Australia, NZ, Canada) is 250 mL. A US customary cup is approximately 240 mL.
3. How do I convert 2 cups to milliliters?
For US cups: 2 cups × 240 mL/cup = 480 mL. For metric cups: 2 cups × 250 mL/cup = 500 mL.
4. What is 1/2 cup in milliliters?
A US half-cup is 120 mL. A metric half-cup is 125 mL.
5. What is 3/4 cup in mL?
3/4 of a US cup is 180 mL. 3/4 of a metric cup is 187.5 mL.
6. How many mL is a UK cup?
The modern UK uses the metric cup of 250 mL. The older Imperial cup is about 284 mL but is rarely used in contemporary recipes.
7. Do I use the same conversion for dry and liquid ingredients?
The volume conversion (cup to mL) is the same, but measuring dry ingredients by volume (cups) is inherently less accurate than by weight (grams). For liquids like water or milk, the mL conversion is perfect.
8. How can I measure mL without a measuring jug?
While not ideal, you can use standard utensils: 1 tablespoon = ~15 mL. So, 16 tablespoons ≈ 240 mL (1 US cup). A teaspoon is 5 mL.
9. Is a “coffee mug” a valid cup measurement?
No. A “cup” in cooking is a standardized unit, not the random size of your drinking mug. Always use proper measuring cups.
10. My recipe is from Australia and says “1 cup.” How many mL is that?
Australian recipes use the metric cup. 1 Australian cup = 250 mL exactly.
11. What is the easiest way to convert cups to mL?
Use a simple multiplier: multiply cups by 240 for US recipes, or by 250 for metric/Australian/UK recipes.
12. How many milliliters are in 1.5 cups?
1.5 US cups is 360 mL. 1.5 metric cups is 375 mL.
13. Why is cup measurement so confusing?
Because different countries adopted different standards (US Customary vs. Metric) for the same unit name (“cup”). Always try to identify the recipe’s country of origin.
14. Can I use an online cups to ml converter for baking?
Absolutely. A reliable online cups to ml converter or cups to ml calculator is an excellent tool. Just ensure you can select the correct cup type (US or metric).
15. How much is 1/3 cup in mL?
1/3 US cup is approximately 80 mL. 1/3 metric cup is approximately 83.3 mL.

4 US cups = 960 mL. 4 metric cups = 1000 mL (which is 1 liter).
17. Are Canadian cups the same as US cups?
Modern Canadian recipes typically use the metric cup (250 mL) or direct metric weights. Some older recipes may use the Imperial system. When in doubt, 250 mL is a common standard in Canada now.
18. How do I convert milliliters back to cups?
Divide the milliliter amount by the cup size. For US: mL ÷ 240 = cups. For metric: mL ÷ 250 = cups.
19. Is a cup of flour the same mL as a cup of water?
Yes, in terms of volume. Both take up 240 mL of space in a measuring cup. However, their weights are drastically different.
20. Where can I find a free printable cups to mL chart?
Many cooking websites offer them. Search for “cups to milliliters conversion chart pdf” to find a downloadable and printable version for your kitchen.
