About the ounces to grams converter
An ounce reading from a scale measures mass. It is suitable for an ingredient or parcel measured by weight, but a fluid-ounce mark on a bottle measures volume. You cannot exchange those two quantities without information about the substance's density.
One ounce is exactly 28.349523125 grams, so 8 oz is 226.796185 g. To convert ounces to grams, multiply by 28.349523125; to convert back, multiply by 0.0352739619.
The avoirdupois ounce is 1/16 of a pound, exactly 28.349523125 g. Because both units are defined exactly, the factor above is exact and the results here carry no conversion error.

Questions
When would I convert ounces to grams?
An ounce reading from a scale measures mass. It is suitable for an ingredient or parcel measured by weight, but a fluid-ounce mark on a bottle measures volume. You cannot exchange those two quantities without information about the substance's density.
How many grams are in a ounce?
One ounce is exactly 28.349523125 grams. The avoirdupois ounce is 1/16 of a pound, exactly 28.349523125 g.
How do you convert ounces to grams?

How accurate is the ounces to grams converter?
Accuracy depends on your inputs and the method's assumptions. Decimal arithmetic uses 50 significant digits, but estimates, numerical methods and source data can be less precise; the displayed rounding does not remove those limits. It is checked against 3 worked examples whose answers come from independent sources; for example, “8 oz to g” is checked against Exact-fraction computation from the legal unit definitions (scripts/gen-pairs.py, Python fractions).
Where does the method come from?
NIST SP 811 (2008), Guide for the Use of the International System of Units, Appendix B; NIST Handbook 44, Appendix C: General tables of units of measurement; BIPM, The International System of Units (SI Brochure), 9th edition.
