When following recipes, accurate measurements are crucial to achieving delicious results. But what happens when your recipe calls for cups, and you’re used to measuring in milliliters? Converting 1 cup to milliliters is one of the most common kitchen challenges, especially for cooks and bakers working with recipes from different countries.
The quick answer? 1 US cup is equal to 240 milliliters.
In this guide, we’ll explore the different types of cups, how they convert to milliliters, and why it matters. Plus, you’ll find a handy conversion chart to make your time in the kitchen even easier.
Let’s dive into the world of cups and milliliters!
Understanding the Cup Measurement
A “cup” might seem like a universal measurement, but it varies depending on where you are in the world. Understanding these differences is key to making accurate conversions.
Types of Cups
- US Cup (Standard)
- Used in most American recipes.
- 1 US cup = 240 milliliters.
- Metric Cup
- Commonly used in countries that follow the metric system (e.g., Australia, New Zealand).
- 1 Metric cup = 250 milliliters.
- UK Cup (Imperial Cup)
- Used in older British recipes, though now largely replaced by metric measurements.
- 1 UK cup = 284 milliliters.
Why These Differences Matter
Using the wrong type of cup measurement can throw off your recipe, especially in baking, where precision is crucial. For example:
- If your recipe calls for 2 cups of liquid using US cups but you measure with metric cups, you’ll end up with 20 milliliters extra per cup, which could impact your final result.
Tip for International Recipes
When following a recipe, check where it originated. Recipes from the US typically use US cups, while those from Australia or Europe often use metric cups.
Conversion Formula
Converting cups to milliliters is simple once you know the type of cup your recipe uses. Here’s the formula for each cup variation:
US Cup to Milliliters
1 US cup = 240 milliliters
Formula:
Milliliters = Cups × 240
Example:
If a recipe calls for 2 US cups of liquid:
2 × 240 = 480 milliliters
Metric Cup to Milliliters
1 Metric cup = 250 milliliters
Formula:
Milliliters = Cups × 250
Example:
If a recipe calls for 1.5 metric cups of liquid:
1.5 × 250 = 375 milliliters
UK Cup to Milliliters
1 UK cup = 284 milliliters
Formula:
Milliliters = Cups × 284
Example:
If a recipe calls for 3 UK cups of liquid:
3 × 284 = 852 milliliters
Quick Tip
If you’re unsure which type of cup your recipe uses, use US cups as the default for most online recipes, unless specified otherwise.

Practical Examples
Understanding how to use the Cups to Milliliters Conversion Chart can make your cooking and baking more precise. Let’s look at a few real-world scenarios where these conversions are helpful.
1. Following a US Recipe with Metric Tools
Suppose your recipe calls for 1.5 cups of milk, but your measuring cup is marked in milliliters. Using the US conversion:
1.5 cups × 240 ml = 360 ml
You’ll need 360 milliliters of milk to match the recipe.
2. Adapting an Australian Recipe in the US
An Australian recipe asks for 2 metric cups of flour. Using the metric conversion:
2 cups × 250 ml = 500 ml
If your measuring cup is in milliliters, measure out 500 ml of flour.
3. Adjusting a British Recipe with US Measurements
A British recipe requires 0.5 UK cups of sugar. Using the UK conversion:
0.5 cups × 284 ml = 142 ml
This means you’ll need about 142 milliliters of sugar.
4. Scaling Recipes
You want to double a recipe that calls for 0.25 US cups of oil. First, convert to milliliters:
0.25 × 240 ml = 60 ml
Double the measurement:
60 ml × 2 = 120 ml
You’ll need 120 milliliters of oil for the doubled recipe.
Tips for Accurate Conversions
- Use a liquid measuring cup for precise liquid measurements.
- For dry ingredients, use a dry measuring cup and level off with a knife for accuracy.
- Always double-check which type of cup measurement your recipe uses to avoid errors.
FAQ Section
1. How many milliliters are in 1 cup?
- US Cup: 1 US cup equals 240 milliliters.
- Metric Cup: 1 metric cup equals 250 milliliters.
- UK Cup: 1 UK cup equals 284 milliliters.
2. Are all cups the same size?
No, the size of a “cup” varies by region:
- US recipes use 240 ml as 1 cup.
- Metric recipes (Australia, New Zealand) use 250 ml as 1 cup.
- UK recipes (older ones) use 284 ml as 1 cup.
3. How do I convert cups to milliliters for liquids and dry ingredients?
The formula is the same:
Milliliters = Cups × Conversion Factor (e.g., 240 for US cups)
However, for dry ingredients, weight (grams) might be a more accurate measure.
4. Can I use a kitchen scale instead of converting cups to milliliters?
Yes! A kitchen scale is highly accurate for both liquid and dry measurements. Convert cups to milliliters first, then pour and weigh the exact amount.
5. Why do recipes use cups instead of milliliters or grams?
Cups are a convenient, volume-based measurement system commonly used in the US. Other regions prefer metric measurements (milliliters, grams) for greater precision.
6. What is the easiest way to convert cups to milliliters?
- Use a conversion chart like the one in this post.
- Alternatively, use the formula: Milliliters = Cups × Conversion Factor.
For example, for US cups: 2 cups × 240 = 480 ml.
