Recipe Conversion Basics

We want to help cooks around the world prepare Allrecipes favorites.

All of the recipes at use volume measurement for ingredients. Any recipe can be converted to metric measurements by selecting the Metric button located under the Servings and Scaling information and clicking the "Change" button.

What's in a Name?

What many cooks may not know is that "standard" measurements--cups, teaspoons, quarts--differ between countries. One cup in the United States is different than one cup in the United Kingdom or in Australia and New Zealand.

  • In the U.S., one cup (8 fluid ounces) = 237 milliliters
  • In the U.K., one cup = 227 milliliters, or .96 U.S. cups
  • In Australia, one cup = 250 milliliters

(Note that an Imperial Pint = 2.5 Imperial Cups, while in the U.S., a pint is only 2 cups).

Standard Measures

Need a refresher on how many cups are in a quart, or teaspoons in a tablespoon?

Taking Temperatures

In degrees Fahrenheit, water freezes at 32 degrees and boils at 212 degrees (at sea level). In degrees Celsius, water freezes at 0 and boils at 100 degrees.

Baking on High

High elevations can cause problems when baking. Learn how to adjust your ingredients for high-altitude baking.

Volume vs. Weight

The saying, "A pint's a pound, the world around" may hold true for water, but don't think it works for every ingredient in your recipe. A cup of flour, sugar, butter and salt all weigh different amounts.

I have a recipe that calls for 8 oz. of eggs. How many is that? Or do I just start breaking them in a measuring cup till it reaches 8 oz? Seems like too much. Recipe only makes one dozen muffins.

How do I determine the correct baking time for a cheesecake when using 2 6.5 inch springform pans rather than my usual 9 inch?

Conversion are a pain and an unnecessarily action. All you have to do to go Metric in the Kitchen is to use Metric 'cups' and 'spoons'. How come it is so dang hard looking and buying anything Metric in America? I mean come on, the same companies that sell in America sell around the World, too, and they sell metric products everywhere, so why do they not sell those same products here, too? All the products are made over seas anyway. America do not want to make things anymore, and yet we are forced to buy and have two sets of tools (garage not kitchen) in our household and companies, Funny is it not? The recipes would not change any at all, you can use the same 'cup' and 'spoon', but it would be a Metric 'cup' and not an American 'cup'. The ratio would be the exactly the same, but you may end up with a little bit more, because the Metric 'cup' is 250 ml vs. the 237 ml American 'cup'. There would absolutely no difference in 'taste'. The only difference in the recipes would be the

what's the rule when you double a recipe?

MetricCook, here in the good ol' U.S. of A., about the only people who use metrics are scientists, mechanics, and track and field athletes. Many years ago, getting Americans to "go metric" was tried, but the attempt was a dismal failure. Gary, I'm not sure what you mean by "What's the 'rule' when you double a recipe?" There is no "rule," you just double the measurements of the original recipe, that's all.

Lewiz, this is for you. A little long but hope it is useful now and in the future. Before beginning this section, a few words are in order. Chocolate is very sensitive to work with. The following will help you work better with it. First, use the best possible chocolate you can afford. Never, use a chocolate flavoured substitute or a synthetic. They are not the same, regardless of what anybody may say. Chocolate comes from the cocoa bean, and contains the entire natural "cocoa butter," and should have no, or very little, additives. Cocoa is a powdered form of chocolate with some of the cocoa butter removed. It is a very good replacement for unsweetened chocolate, but it requires a little work first. To substitute cocoa powder for one square of unsweetened chocolate, use the following recipe: 45 gr/3 tbsp pure cocoa powder 15 gr/1 tbsp unsalted butter In a small saucepan, over a low heat, melt the butter, or shortening. Stir in the cocoa powder, until

how many bananas make a cup?

Why isn't this in user settings? The only reason I signed up for an account was that I thought the site could remember what measurement system I want. Clicking on convert to metric on every recipe is so annoying that I'm making a comment about it.

I see a lot of questions but where are the answers? I am another frustrated cook that would like have a "convert to metric" option on each recipe. It will be interesting to see if a reply is posted. thank you
