Frequently asked questions
How many grams is 1 ounce exactly?
The avoirdupois ounce is defined as exactly 28.349523125 grams — one sixteenth of the pound, which is itself defined as 453.59237 g. Dividing grams by 28.349523125 therefore gives the exact ounce value.
What is the formula for grams to ounces?
oz = g ÷ 28.349523125. For example, 100 g ÷ 28.349523125 = 3.527396195 oz. The reverse direction multiplies by 28.349523125: 8 oz × 28.349523125 = 226.796185 g.
Are these weight ounces or fluid ounces?
Weight ounces (avoirdupois), the ones US recipes and postal scales use. Fluid ounces measure volume — 1 US fl oz ≈ 29.57 milliliters — and are a different unit; do not swap them when baking, or ratios will be off.
Do you store the weights I convert?

About this tool
This free grams to ounces converter is aimed at the kitchen scale generation: recipes from American blogs written in ounces, coffee beans dosed in grams, sourdough hydration math, protein servings, jewellery weights and postal rates. It uses the exact avoirdupois definition — 1 ounce = 28.349523125 grams, one sixteenth of the internationally defined pound — so the conversion is grams ÷ 28.349523125 with nothing approximate in between. Results update on every keystroke, the full equation is printed under each one, and the ten-significant-digit display is precise enough that bakers can scale a dough formula up or down without drift. Anchors for quick mental checks: 100 g = 3.527396195 oz, 250 g ≈ 8.82 oz, 500 g ≈ 17.64 oz, and going the other way 8 oz = 226.796185 g. One caution this page makes easy to honor: kitchen "ounces" in US recipes are avoirdupois weight ounces, exactly what this tool converts — fluid ounces measure volume and belong to a different table. As everywhere on this site, the calculation runs entirely in your browser: ingredient amounts, parcel weights and anything else you enter are never uploaded, stored or logged. To convert ounces back to grams, swap the From and To selects in one click.
