Ounces (oz) to Grams (g) Converter
General-purpose weight converter for kitchen and postal needs. Instantly converts Avoirdupois Ounces to Grams.
About
In culinary arts and international shipping, the distinction between weight systems is a frequent hurdle. This tool converts Avoirdupois Ounces (the standard US unit for solid weight) to Grams (metric). Accuracy is paramount here; baking recipes often fail if precise gram measurements are replaced by rounded ounce approximations.
Important distinction: This calculator handles Weight ounces. It does not convert Fluid ounces (fl oz), which measure volume. Using this tool for liquids (like water or milk) without knowing the density will yield incorrect results. The conversion factor used is the international standard: 1 oz = 28.34952 g.
Formulas
The conversion is linear using the definition of the international yard and pound agreement (1959).
