Convert grams to ounces instantly with a live calculator, a cooking and deli reference chart, and the manual math.
Recipes are the biggest reason people convert grams to ounces. European and Australian recipes measure flour, sugar, and butter in grams, while American recipes use ounces (and cups). A person following a US recipe with a European scale, or vice versa, converts almost every ingredient. Chocolate is a classic example: the bar says 100 g on the package but the recipe asks for 3.5 ounces.
Deli and grocery weights are the other common case. In the US, meat, cheese, and produce are sold by the pound and ounce; in most other countries, they are weighed in grams. Pet food portions, supplements, and jewelry are also measured in grams internationally but ounces in the US, so this simple division is more common than people think.
