Before you rely on it
Weight ounces, not fluid ounces or troy ounces
This page converts to the ordinary avoirdupois ounce, exactly 28.349523125 grams — the ounce on a kitchen scale or a food package. Its reciprocal never ends, so the answers here are rounded.
The fluid ounce measures volume, not weight. 100 g of water happens to be about 3.4 fl oz, but 100 g of flour or honey is not; for liquids by volume, use the milliliter pages.
Gold, silver and other precious metals are priced per troy ounce, about 31.10 g — some 10 percent heavier. A price per ounce for bullion is almost always per troy ounce, which this page does not convert.
US nutrition labels round 1 oz to 28 g. A serving of "1 oz (28 g)" is the labelling convention, not a different ounce.
