Ounces to grams, baking without broken recipes
Recipes from the US measure in ounces, most kitchen scales read grams, and baking punishes sloppy factors. The exact number: 1 oz = 28.349523125 g (one sixteenth of a pound, which is 453.59237 g exactly).
This page presets the converter to ounces → grams. Type 8 and you get 226.796 g — a stick-and-a-half of butter, a standard chocolate bar, half a pound of anything.
One warning this page exists to solve: fluid ounces measure volume, not weight, and the two are only interchangeable for water. Use this converter for solids — flour, sugar, chocolate, packages. The quick table covers the common recipe amounts, computed locally in your browser.

FAQs about this conversion
How many grams is 1 oz exactly?
1 oz = 28.349523125 g — one avoirdupois ounce, defined through the exact pound of 453.59237 g.
Is a fluid ounce the same as an ounce?
No. A fluid ounce measures volume (29.5735 mL in the US system); an ounce measures mass. They coincide only for water-like densities, so weigh dry ingredients with this converter, never measure them in fl oz.
What is 4 oz in grams?
4 oz = 113.398 g — a standard stick of butter in metric terms, and a useful baking anchor.
