How it works

Any recipe, in the measures you use

  1. Paste the link and your email
  2. Mise reads the recipe for you
  3. Open it and pick metric or US

Cups to ml

When you only need one amount, this is what US cups come to in millilitres. The converter above does every ingredient in the recipe at once.

US cupsMillilitres
⅛ cup30 ml
¼ cup59 ml
⅓ cup79 ml
½ cup118 ml
⅔ cup158 ml
¾ cup177 ml
1 cup237 ml
2 cups473 ml
3 cups710 ml
4 cups946 ml

A US cup is 236.6 ml. Australian and New Zealand recipes use a metric cup of 250 ml, and older British recipes sometimes an imperial cup of 284 ml, so check where a recipe comes from before you measure.

Oven temperatures are rounded to a setting an oven actually has: 350°F is 176.7°C, and nobody sets an oven to that.

Converting a recipe well

Most of a conversion is arithmetic. These are the parts where recipes and converters go wrong.

A cup of flour has no one weight

Scooped, spooned or sifted, a cup of flour weighs anywhere from about 120 to 150 g. So Mise turns cups into millilitres and never guesses a weight. When a recipe gives weights, you get grams.

Ounces and fluid ounces differ

An ounce is a weight and a fluid ounce is a volume. Recipes use both, sometimes in the same list. Mise keeps them apart, so 8 oz of cheese becomes 227 g and 8 fl oz of milk becomes 237 ml.

Spoons are almost the same

A US tablespoon is 14.8 ml and a metric one is 15 ml. For cooking the difference doesn't matter, so a spoon stays a spoon.

Fan ovens run hotter

American recipes are written for conventional ovens. With a fan oven, set it about 20°C lower than the converted temperature.

Cook it in Mise

The recipe you get by email opens on the web, where you can scale it and switch units. In the Mise app the original recipe is always one tap away, and you can also adapt it to your taste, cook it step by step with timers, and keep it with all your other recipes, always available. More about Mise
