American vs Standard

Unlike other countries, America doesn’t use grams for recipes and measuring the weight of foods. They only use this unit when they are manufacturing a food item or trading it internationally. Besides grams, litres is the unit that is commonly used for manufacturing and trade. 

In American recipes, you’ll see the ingredients written as ounces. For many recipes (desserts, main courses, or breakfasts), you’ll notice cups and tablespoons as the sole unit of measurement. However, if you live outside of America, or want a more accurately measured recipe, understanding the ounce to grams conversion is essential.

How to measure dry weight?

The best way to measure dry weight is to use a simple kitchen scale (also known as a food scale). It is so simple to use- all you do is select the ‘tare’ button which sets the scale at zero. From there, you can start adding dry ingredients and it will provide an accurate weight.

Alternatively, if you want to measure butter, sugar or flour (like for cakes or brownies), you’ll also need measuring spoons and cups. While adding flour, sugar or butter to the measuring cups, press it with a flat tool or knife to remove the extra ingredient. Then put the container or measuring cup on the kitchen scale to calculate its dry weight.

  1. You’re information is helpful to an extent. I purchased a supplement that says to take 5 grams daily…how do I measure.17 ounces??

  2. This might sound ungrateful, Arman (definitely not intended to be); but I am still looking for a direct cup to gram conversion. Will you be able to offer this?
    I have noticed that some recipe sites have a metric option that you can click on, that immediately gives you the grams equivalent. Is this a possibility?
    Otherwise I shall keep plodding on with Ye Olde “copy and paste” 😬😝, as you are definitely worth it!

  3. Thank you so much for all the helpful emails! There is no telling how many times I’ve gotten measurements wrong because I did not have this information. I love all the recipes you send!
