Nothing is more frustrating than finding THE perfect recipe, getting all the ingredients, and being ready to bake, only to find out the recipe uses conversions you don’t recognize. 

This happens to me ALL the time, and since I don’t have every unit conversion memorized (shocking, I know), I decided to create some handy cooking resources. The next time you find the perfect brownies recipe, you can get straight to baking!

How many grams are in an ounce? The quick answer

One ounce contains 28 grams. For a more precise conversion, 1 ounce is equal to 28.3495 grams. 

Follow the simple formula to convert grams to ounces easily:

Weight in ounces = weight in grams / 28.34952 

For example, if you have 5 grams and want to convert them to ounces, you’ll get 0.17637 ounces by using this formula. 

What is a gram?

A gram (abbreviated as g) is a unit of weight used in the metric system. One gram is equal to 1,000 milligrams (mg), and it takes 1,000 grams to equal 1 kilogram (kg). Most recipes use grams as the metric system, which is the most commonly used system of measurement.

What is an ounce?

An ounce (abbreviated as oz) is a unit of measurement for weight. Ounces are used in America and other countries that follow the US customary system or British Imperial system (including Liberia and Myanmar). It takes 16 ounces to equal 1 pound (lb).

Tips for measuring dry weight

The best way to measure dry weight is to use a simple kitchen scale. Food scales are one of the most versatile kitchen tools because they allow you to bounce back and forth between units and get accurate measuring for wet and dry ingredients like flour, brown sugar, or honey. 

Here are the steps needed to get precise measurements with a digital scale:

  1. Place a bowl on the scale
  2. Turn the scale on (if the scale is already on, press ‘tare’ button to zero out the weight of the container)
  3. Select your desired unit
  4. Add the ingredients to the bowl until you reach the desired 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!
