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.

Cup standard

Metric (250 mL) is commonly used in Canada, the UK, Australia, and New Zealand; US cups are ~236.588 mL.

Converted value 250 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.

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.

How CupsToML handles measurement standards

Last reviewed: April 18, 2026

CupsToML is independently run for home cooks and bakers. The site aims to be practical and transparent: it uses a clear kitchen default when one is needed, shows where a different standard changes the answer, and points you to a guide or chart when a quick number is not the whole story.

If you want the short standards summary behind these numbers, use Kitchen Measurement Standards and About CupsToML.

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 Metric cup, used in Canada, Australia, the UK, and New Zealand, holds 250 mL. A US cup holds 236.6 mL. That is a 13.4 mL gap per cup. For a single cup of milk it barely matters; for a double-batch of a batter using three cups of liquid, the difference becomes 80 mL, 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.

  1. Set From to Cup.
  2. Set To to mL.
  3. Choose your cup standard: Metric (250 mL) if the recipe is from a Canadian, Australian, UK, or New Zealand source; US (236.6 mL) if the recipe is from an American cookbook or site.
  4. Enter 2 in the Amount field.
  5. The result appears immediately: 500 mL for Metric cups, or 473.2 mL for US 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

For cleaner measuring, round to the nearest practical tool: 1/4 tsp, 1/2 tsp, 1 tsp, 1 tbsp, etc.

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.

Common kitchen conversions at a glance

These values cover the measurements you will reach for most often. The 1/2 cup and 1/4 cup rows show both Metric and US values side by side so you can see where the standards diverge in practice.
