What Is the Grams to Ounces Calculator?
This tool converts a mass measured in grams (g) into avoirdupois ounces (oz), the unit used for everyday weight in the United States and parts of the UK. It uses the internationally defined relationship where one ounce equals exactly 28.349523125 grams, so the result is precise rather than an approximation.
How to Use It
Type the number of grams you want to convert into the input box and the calculator instantly returns the equivalent weight in ounces. It works for any value — a few grams of spice, hundreds of grams of flour, or kilogram-scale quantities entered in grams.
The Formula Explained
The conversion divides grams by the number of grams in one ounce:
$$\text{ounces} = \frac{\text{grams}}{28.349523125}$$
Because there are more grams than ounces in a given weight (a gram is smaller), dividing always gives a smaller number than the gram value you started with.
Worked Example
Suppose you have 100 grams of coffee beans. Divide by 28.349523125: $$100 \div 28.349523125 \approx 3.5274 \text{ ounces}.$$ So 100 g is roughly 3.53 oz. A quicker mental estimate is "grams \(\times 0.035\)".
