Cup size
Quick amounts
Need grams for flour or sugar, not just volume? Use the cups to grams converter — cup size still matters, but density changes the weight.
Why cup size matters
A “cup” is not universal. American test kitchens and FDA references use 240 mL. Australian and Canadian home cooks often learn on 250 mL cups. If you convert 2 cups without checking which standard the author meant, you can be off by 20 mL — noticeable in panna cotta, simple syrup, or cocktail ratios.
For baking weights, volume in mL still does not tell you grams. After you know the liquid volume, switch to the cups to grams converter when the ingredient is flour, sugar, or cocoa.

11/2 cups in mL and missing-slash fractions
Search boxes and recipe notes often drop or move the slash, so 11/2 cups in mL, 1 1 2 cup to mL, and 1 1/2 cups to mL usually point to the same kitchen amount: one and a half cups. With the US cup setting, 1 1/2 cups is 360 mL. With a metric cup, it is 375 mL.
The same pattern applies to 1 1 3 cup for 1 1/3 cups and 1 1 4 cup for 1 1/4 cups. A search like 13 cup to mL is ambiguous: if the recipe meant 1/3 cup, use 80 mL US or about 83 mL metric; if it truly meant 13 cups, enter 13 in the calculator above. If the recipe comes from the US, choose the 240 mL cup standard unless the author says metric or Australian cups.
115 mL to cups
115 mL is about 0.48 US cup, which is just under 1/2 cup (120 mL). For a sauce, milk, broth, or water in an everyday recipe, measure a scant 1/2 cup. If the recipe uses a metric 250 mL cup, 115 mL is about 0.46 cup. This is a volume conversion, so the mL result stays the same for milk and water; only the weight in grams changes by ingredient.

FAQ
- How many mL in a US cup?
- A US legal cup is 240 milliliters (about 8.12 US fluid ounces). That is the standard used on this site for dry and liquid US recipe measures unless a card specifies otherwise.
- Is a metric cup 250 mL?
- Yes. Australia, New Zealand, and many European home references use a 250 mL cup. One metric cup is about 4% more volume than a US cup — enough to matter in custards or gelatine.
- Should I use a dry or liquid measuring cup?
- For water, milk, and broth, use a clear liquid cup with the meniscus at eye level. For flour or sugar, this page only converts volume — use the cups to grams tool when you need weight on a scale.
- How many mL is 1/2 cup?
- In US recipe measurements, 1/2 cup is 120 mL. With a metric cup standard, 1/2 cup is 125 mL.
- How many mL is 2/3 cup of milk?
- Two-thirds of a cup of milk is 160 mL with a US cup or about 167 mL with a metric cup. Milk and water use the same cup-to-mL conversion because milliliters measure volume.
- How many mL is 1 1/2 cups?
- In US recipe measurements, 1 1/2 cups is 360 mL. With a metric cup standard, 1 1/2 cups is 375 mL.
- How many cups is 115 mL?
- 115 mL is about 0.48 US cup, so it is just under 1/2 cup. For everyday recipe use, round it to a scant 1/2 cup; with a metric 250 mL cup, it is 0.46 cup.
- How many mL is 11/2 cups?
- When a recipe search says 11/2 cups, it usually means 1 1/2 cups. That is 360 mL with a US cup or 375 mL with a metric cup. If the recipe truly means eleven and a half cups, use the calculator input instead.
- How many mL is 1 1/3 cups?
- In US recipe measurements, 1 1/3 cups is about 320 mL. With a metric cup standard, 1 1/3 cups is about 333 mL.
- How many mL is 1 1/4 cups?
- In US recipe measurements, 1 1/4 cups is 300 mL. With a metric cup standard, 1 1/4 cups is 312.5 mL.
- Do water and milk change the cup-to-mL conversion?
- No. Milliliters measure volume, so 1/2 cup of water and 1/2 cup of milk are both 120 mL with the US cup setting. Weight in grams changes by ingredient density, but volume in mL does not.
- Does 1 cup of flour equal 240 mL of flour by weight?
- A US cup of water is about 240 g, but a cup of flour weighs far less (often near 120–130 g spooned). Volume in mL does not equal grams unless you know the ingredient density.
