Grams to Ounces Calculator
This converts weight (dry) ounces, the kind used for solid ingredients and postage. It is not the same as fluid ounces, which measure volume. For fluid ounces, use a volume converter instead.
To convert grams to ounces, divide the number of grams by 28.35. One ounce equals 28.35 grams, so 100 grams is 3.53 ounces and 500 grams is 17.64 ounces. Because both grams and ounces measure weight, this conversion is exact and does not depend on the ingredient, unlike ml to grams which needs density.
How many grams are in an ounce?
There are 28.3495 grams in one ounce, usually rounded to 28.35 grams. This is the number you divide by when converting grams to ounces. Going the other direction, one gram is 0.03527 ounces.
How to Convert Grams to Ounces
The formula is: ounces = grams ÷ 28.35.
One ounce is defined as 28.349523125 grams, which almost everyone rounds to 28.35. To go from grams to ounces, you divide. For example, 250 grams ÷ 28.35 = 8.82 ounces.
Unlike volume conversions, this one is the same for every substance. 100 grams of flour, 100 grams of sugar, and 100 grams of water are all 3.53 ounces, because you are converting weight to weight. The ingredient does not matter.

Grams to Ounces Is Weight, Not Fluid Ounces
There are two kinds of ounces, and mixing them up gives the wrong answer.
A dry ounce, also called a weight ounce, measures mass. This is what you use for flour, sugar, meat, or anything you put on a scale. 1 dry ounce is 28.35 grams. This calculator uses dry ounces.
A fluid ounce measures volume, like a liquid in a measuring cup. 1 fluid ounce is about 29.57 ml. You cannot convert grams straight to fluid ounces without knowing the density of the liquid.
If your recipe lists “oz” for a solid ingredient, it means weight ounces, and this converter is correct. If it lists “fl oz” for a liquid, you need a volume converter.
