Cups to mL Converter and Kitchen Conversions
Need cups to mL fast? The main tool below starts there by default, so you can get the jug-friendly number first and keep moving.
You can switch the same tool to tablespoons, teaspoons, liters, grams, ounces, and oven temperatures when the recipe calls for something else. The rest of the page stays below the fold for standards help, common references, and broader kitchen conversions.
Quick cups to mL converter
It opens on cups to mL because that is the most common kitchen check on the site. Change the units only if you need a different conversion.
Use 240 mL for practical US recipe math, 236.588 mL for exact US customary conversions, or 250 mL when the recipe uses a Metric cup.
Converted value 240 mL
Why Home Cooks Keep Coming Back
CupsToML works best when you need more than a one-off number. It helps when recipes switch standards, when batch sizes change, and when you want your second attempt to turn out like your first.
Match recipe standards
Switch between Metric and US cup values when the source recipe and your measuring tools do not line up.
Scale without drift
Convert once, then scale from the converted total so repeated rounding does not creep into the recipe.
Get the why, not just the number
Use the guides when you need to understand why cups, ounces, grams, and temperatures behave differently.
Practical note: We aim for mathematical accuracy, but in a real kitchen it is often best to round to the measuring tool you actually have in front of you.

Why accurate measuring matters in the kitchen
Small measurement differences add up faster than most recipes expect. A cup of all-purpose flour scooped directly from the bag packs in about 20 to 30 percent more flour than the same cup spooned and leveled. That is the difference between a tender crumb and a dense, dry loaf, and it comes entirely from how the cup was filled, not the recipe itself.
Cup standards add another layer of variation. A practical US recipe cup is commonly treated as 240 mL, an exact US customary cup is about 236.6 mL, and a Metric cup holds 250 mL. For a single cup of milk the gap is small; for a double-batch of batter using several cups of liquid, it can be enough to change the consistency.
The practical tip: when a recipe gives you a volume in mL, measure in mL. Do not convert to cups and back. The converter above handles region-aware conversions, but the most reliable path is to use the unit the recipe author used.
How to use the converter
The main converter updates as you type. The default path is the most common one: a recipe calls for cups, and you want the mL total before you fill the jug.
- Set From to Cup.
- Set To to mL.
- Choose your cup standard: US recipe (240 mL) for practical American recipe math, exact US customary (236.6 mL) when precision matters, or Metric (250 mL) when the recipe says metric cup.
- Enter 2 in the Amount field.
- The result appears immediately: 480 mL for the practical US recipe setting, 473.2 mL for exact US customary, or 500 mL for Metric cups.
The same flow works for weight and temperature too. Change the units when you need another kitchen conversion, and the result updates instantly without a page reload.
Tips
Scaling for Meal Prep: Converting volume to weight (grams) makes it easier to scale recipes consistently for large batches.
Decimals are exact; measuring tools aren’t. Rounding to common fractions is often the practical choice.
