Ounces to Grams Converter
This is a mass conversion using the avoirdupois ounce. The calculator uses a fixed, transparent conversion factor and does not create separate pages for every numeric value.
grams
28.34952313 g
grams = ounces × 28.349523125
Formula
grams = ounces × 28.349523125
This conversion is deterministic. Pages that would require an unspecified ingredient density are intentionally not published.

Measurement notes
Kitchen conversions are safest when source and target units describe the same physical quantity. Volume-to-volume and mass-to-mass conversions use fixed factors, so this page can give a direct result without asking what ingredient you are measuring.
Weight-to-volume conversions are different. A cup of flour and a cup of honey do not weigh the same amount, so a generic grams-to-cups formula would be misleading. This site only publishes those conversions when the ingredient or density assumption can be stated clearly.
For practical cooking, rounded measuring tools may be less precise than the mathematical result. Use the displayed number as a conversion reference, then round appropriately for the recipe and measuring equipment you have.
US customary, Imperial, and metric units can share similar names but use different definitions. Check the labels on your recipe and measuring tools when precision matters, especially for cups and fluid ounces.
Frequently asked questions
How do I convert oz to g?
Use the formula grams = ounces × 28.349523125. Enter any nonnegative amount in the converter above for an instant result.
Can I use decimals?
Yes. Decimal inputs are supported, including values such as 0.25, 1.5, and 2.75.
Does this convert weight or volume?
This is a mass conversion using the avoirdupois ounce.
Why can kitchen measurements differ?
Cup, tablespoon, teaspoon, fluid-ounce, and ounce definitions are not interchangeable across every measurement system. This page states the unit system it uses so you can avoid mixing US, Imperial, metric, weight, and volume values.
