A standard cup of milk weighs approximately 240 to 250 grams, with slight variations depending on the type (whole, skim) and if it's a US or metric cup, but around 240g (US Cup) or 250g (Metric Cup) is a reliable general estimate for recipes.
Liquid Ingredient Conversions
While brownies don't usually need many liquid ingredients, it's good to know the conversions for common liquids used in baking: 1 cup water or milk = 240ml = 240g.
Cups to millilitres
For liquids 1 cup is the same as 240ml (US) or 250ml (UK) - there will be no difference to the quality of your baking based on the 10 ml difference. For simple conversions for measurements of less than 1 cup we have prepared a cups to ml conversion table for you below.
For example, one cup of milk weighs about 225 grams. Of that weight, 2% milk holds 5 grams of fat and whole milk contains 8 grams. So whole milk isn't much fattier than 2%. In fact, a gallon of 2% has more than half the fat as a gallon of whole milk.
There are 0.845 cups in 200 milliliters.
1 cup can be 240 ml or 250 ml depending on the measurement system: US recipes typically use 240 ml (or 236.6 ml for the precise legal cup), while Australian, UK, and many metric recipes use 250 ml, so it's best to check the recipe's origin. For baking accuracy, using weight (grams) is often better, notes this Reddit thread.
No, 250 grams is not always 2 cups; it depends entirely on the ingredient's density, as grams measure weight and cups measure volume, so 2 cups of flour weigh much less than 2 cups of sugar or butter. For example, 250g of all-purpose flour is about 2 cups (since 1 cup is ~120g), but 250g of granulated sugar is only about 1 ¼ cups, while butter is closer to 2 cups.
The density of milk is roughly 1030 g/L depending mostly on the fat content and temperature. That means that if you were to measure milk according to the volume of water, for every liter (~4 cups) of milk you'll be around 30 grams (~1 ounce/2 tablespoons) off.
First of all, we can help with that one: 1 cup is equal to 8 ounces (oz), 16 tablespoons (Tbsp), 48 teaspoons (tsp), or 240 milliliters (mL).
There's no single answer for grams in a cup because it depends on the ingredient's density, but generally, 1 cup of water is about 237-250g, while 1 cup of flour is around 120-125g, and 1 cup of sugar is roughly 200g. Always check a conversion chart for specific ingredients, as a cup measures volume, while grams measure weight, and different items have different densities.
250 grams is equal to 1 metric cup (250ml) for water or similar liquids, but the cup measurement for 250g of dry ingredients varies significantly by density; for instance, it's about 2 cups of flour, slightly over 1 cup of sugar, or 1 ¼ cups of packed brown sugar, because grams measure weight while cups measure volume.

Plus, according to the USDA, 1 cup whole milk contains 219g water and weighs 249g; and 1 cup 2% milk contains 218g water and weighs 238g.
However, in modern recipes, the US legal cup of 240 ml (about 8.45 British imperial fluid ounces or 8.12 US customary fluid ounces) is more commonly used.
Holding a measuring cup makes it hard to get an accurate reading because the liquid contents can slosh around. Instead, start by using an angled measuring cup or angled jigger that allows you to see the measurements from above, and place it on a flat surface so the contents can settle after you pour them in.
A “cup” in American measurements actually is a standard(ish) volume— 8 oz, or a tad less than 240 mL.
Yes, 200 grams is equal to 1 cup for granulated sugar, but it's not the same for other ingredients; 200g of all-purpose flour is about 1.6 cups, while 200g of butter is less than a cup (around 7/8 cup or just under 2 sticks), highlighting that weight (grams) and volume (cups) differ by ingredient density, making a kitchen scale best for accuracy.
Yes, 250ml is equal to 1 cup in many countries like Australia, Canada, and New Zealand (the "metric cup"), but in the US, 1 cup is slightly smaller, about 237-240ml; so, for recipes, check the country of origin, but 250ml is a standard metric cup.
Why Weight (Grams) Gives More Consistent Results
One Australian metric measuring cup holds 250 ml, one Australian metric tablespoon holds 20 ml and one Australian teaspoon holds 5 ml.
How to convert grams to cups. Convert grams to cups by dividing the weight of the ingredient in grams by 237 times the density of the ingredient. Check out the example below to see how the formula for the conversion works. Example: You want to convert 500 grams of butter to cups, which has a density of 0.91 grams.
Volume of most liquids (water, juice, milk, cream) are converted by volume from imperial to metric: 1 cup = 250 mL. ¾ cup = 175 mL. ½ cup = 125 mL.
