Converting Ounces (oz) to Grams (g) is a standard weight / mass conversion used daily in science, engineering, travel, and everyday life. This conversion bridges the imperial and metric systems — one of the most common cross-system unit lookups worldwide.
1 Ounces = 28.349493 Grams. Multiply any Ounces value by this factor to get Grams.
| Ounces | Grams | |
|---|---|---|
| 0.1 oz | → | 2.83495 g |
| 0.25 oz | → | 7.08737 g |
| 0.5 oz | → | 14.1747 g |
| 1 oz | → | 28.3495 g |
| 2 oz | → | 56.699 g |
| 5 oz | → | 141.747 g |
| 10 oz | → | 283.495 g |
| 25 oz | → | 708.737 g |
Key for converting US recipe measurements into metric for international kitchens, or postal weights.
Country usage: Ounces are standard in US food packaging. International food labels use grams or kilograms.
Using 28 g instead of 28.35 — a 1.25% error that compounds in large batches.
Until 2019, the kilogram was the last SI base unit defined by a physical object — a platinum-iridium cylinder kept in Paris. It is now defined by the Planck constant, making it infinitely reproducible.
