Convert Grams to Ounces (g to oz)
1 ounce (avoirdupois, the everyday weight unit) is defined as exactly 28.349523125 grams — not to be confused with the fluid ounce, a unit of volume with a different value.

How it works
This direction is for when you already have a weight in grams — a European recipe ingredient, a kitchen scale reading, a shipping label — and need it in ounces to follow a US recipe or check it against a US-labeled weight limit.
Baking is the most common trigger: a European recipe listing 200 g of butter converts to about 7.05 oz, useful when working from a US kitchen scale that only displays ounces and pounds. Weight-based baking (rather than volume-based cup measures) is generally more accurate, so this conversion matters for anyone following a precise recipe with a US-made scale.
It's worth being careful here: this "oz" is a unit of weight (the avoirdupois ounce), not the fluid ounce used for liquid volume — the two share a name but measure entirely different things and have different numeric relationships to their respective base units. A recipe listing "8 oz flour" means weight (226.8 g), never volume.
Shipping and postage are another common case: many postal services calculate rates by weight in ounces for small parcels, so converting a European package's gram weight — say, 250 g, which is about 8.82 oz — helps estimate a US shipping cost before it's calculated at the counter.
Coffee is bagged in different units on each side of the Atlantic, and the two sets of sizes never line up. A European 250 g bag is 8.82 oz and a 1 kg catering bag is 35.27 oz, while US roasters most often sell a 12 oz bag, which is 340.2 g: more than a 250 g pack and well short of half a kilo. Brewing recipes make the same jump, since an 18 g espresso dose is about 0.63 oz on a US scale that reads in hundredths of an ounce.
Frequently asked questions
- How many ounces is 100 g?
- 100 g equals about 3.53 oz (100 ÷ 28.3495). That is a common recipe ingredient weight, roughly the amount of chocolate in a standard European chocolate bar.
- How do I convert grams to ounces without a calculator?
- Divide the gram value by 28 for a rough estimate. For example, 100 g ÷ 28 ≈ 3.57, close to the exact 3.53 oz.
- Is the "oz" in a recipe for butter or flour the same as a fluid ounce?
- No — this is one of the most common mixups in cooking. The ounce in "8 oz butter" is a weight (avoirdupois ounce, 28.35 g), while a fluid ounce measures volume (29.57 ml) and is used for liquids. They are different units that happen to share a name; a recipe should make clear which one it means, usually by context (solid ingredients are weighed, liquids are measured by volume).
- A package weighs 250 g — roughly how many ounces is that for a US shipping estimate?
- 250 g converts to about 8.82 oz. Many postal services price small parcels in whole-ounce increments, so knowing the ounce figure ahead of time helps estimate cost before an official weigh-in at the counter.
