Ounces to Grams

This is almost always a kitchen conversion, and the ounce meant is the avoirdupois ounce: 28.349523125 grams exactly, one sixteenth of a pound.

Be careful of the trap. A fluid ounce is a measure of VOLUME and is not this unit at all — an ounce of flour and a fluid ounce of milk are different kinds of quantity. If your recipe says "fl oz", you want the volume converter, not this page.

The rows below are the amounts recipes are actually written in.
