Match recipe standards: Switch between Metric and US cup values when the source recipe and your measuring tools do not line up.
Kitchen Conversions Made Simple
You are halfway through a recipe, the measuring jug is out, and the numbers on the page do not match the tools in your hand. That is the moment CupsToML is built for. Use it to switch quickly between cups, mL, grams, ounces, and oven temperatures without stopping to redo the math.
The main tool is right below. The rest of the page is here to help you avoid the small measurement mistakes that make recipes feel inconsistent from one batch to the next.
Universal Converter
Metric (250 mL) is commonly used in Canada, the UK, Australia, and New Zealand; US cups are ~236.588 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.
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 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 Universal Converter updates as you type. Here is the simplest real-world use case: a recipe calls for 2 cups of milk, and you want the mL total before you fill the jug.
- Set From to Cup.
- Set To to mL.
- 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.
- Enter 2 in the Amount field.
- 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 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.
