How to Convert Ounces to Grams When Using Sugar

Updated November 21, 2016

Using recipes from around the world is easy when you have access to the Internet in a globally connected world. When cooking and baking, some recipes use metric measurements. Knowing how to change a measurement from ounces to grams can help you get the recipe ratios just right. When using sugar, you can use simple math to calculate the amount needed.

Write down on a piece of paper how much sugar you will need. Domestic recipes will most likely list sugar measurement in increments of cups, tablespoons or teaspoons.

Convert the measurement in to ounces first. For example, if you need one-half cup of sugar or eight tablespoons, the equivalent measurement in ounces is four ounces. Use the basic formula of sixteen tablespoons of sugar equals one cup of sugar. One cup of sugar equals eight ounces of sugar.

Convert ounces to grams. The equivalent measurement is one ounce of sugar equals 28.3 grams of sugar. For example, one-half cup of sugar, which equals four ounces of sugar, equates to 113.2 grams of sugar. Use a paper and pencil to perform the math and double-check your results.

Use a visual aid to help you verify your measurements are accurate. If you are using a recipe calling for four ounces of sugar, measure out four ounces of sugar using a measuring cup with ounce markings. Pour the contents in to an unmarked bowl. Calculate the equivalent in grams, which is 113.2 grams and pour the contents in to a different bowl. Visually compare to make sure you calculated correctly.

Make adjustments when you may not be able to exactly measure the ingredient. When you are using sugar for baking a sweet dish, you may need to round up slightly to get as close as possible to the gram markings on the measuring utensils you are using. For example, if you need one-half cup of sugar, or four ounces of sugar, and the equivalent in grams is technically 113.2 grams, you may need to round up to 115 grams, depending on the measuring cup you are using. It is acceptable to round up slightly when using sugar.


Keep a list of unit equivalents so you do not have to recalculate every time you need to make a recipe adjustment. You can also use a kitchen scale to measure sugar in grams.


Use caution working around a stove or oven to avoid injury.
