FAQ

Is this for cooking?

Yes — most recipes that switch between metric and imperial use avoirdupois ounces. Note that fluid ounces are a different unit (volume, not mass) and don't convert directly to grams; the relationship depends on the substance's density.

What about troy ounces?

Troy ounces are used for gold, silver, and other precious metals. 1 troy oz = 31.1035 g. This calculator does NOT use troy ounces — use a dedicated gold/silver weight converter for those.

Why the awkward number?

The avoirdupois ounce is defined as exactly 28.349523125 grams. The reciprocal (1 / 28.349523125 ≈ 0.0352739619) gives the grams-to-ounces factor.
