Converting Grams to Ounces (g to oz) is frequently required in the kitchen, especially when using American recipes in countries that use the metric system. The “ounce” used here is the avoirdupois ounce (a measure of weight), not the fluid ounce. 1 Ounce is approximately equal to 28.35 Grams. This conversion is also standard for postage, precious metals (though troy ounces are slightly different), and diet tracking.
*Based on the international avoirdupois ounce (~28.35 g).

g ÷ 28.35 = oz

A standard chocolate bar weighs 100 grams:
100 ÷ 28.35 = 3.53 oz

Frequently Asked Questions
One gram is a very small part of an ounce. Specifically, 1 gram equals 0.03527 ounces. Because this number is so small, most people find it easier to remember the reverse: that there are 28.35 grams in every one ounce.
In small amounts, it might not seem like much. However, if you are measuring 10 ounces of an expensive ingredient or shipping a heavy box, that 0.35 adds up. Over 10 ounces, you’d be off by 3.5 grams—which is the weight of about three and a half paperclips!
