What is Grams to Ounces Converter?
The grams to ounces converter is a precision tool for converting between the metric gram and the imperial avoirdupois ounce. One gram equals 0.035274 ounces, and one ounce equals 28.3495 grams. This conversion is most commonly used in cooking and baking, where recipes from different countries use different measurement systems, as well as in precious metals trading, nutrition tracking, and postal services.
The gram is defined as one thousandth of a kilogram in the SI system, making it a convenient unit for measuring relatively small quantities of food ingredients, chemical substances, jewelry, and postage. The ounce has its roots in the Roman uncia (one twelfth of a Roman pound) and was standardized at 28.3495 grams through international agreement. In the kitchen, the relationship between grams and ounces is perhaps the most important conversion for anyone following recipes from across the globe.
How to Use This Calculator
Enter the weight in grams and the converter instantly displays the equivalent in ounces (and other units). The formula is: ounces = grams divided by 28.3495. For cooking, you can use the simplified approximation of dividing by 28 for quick estimates. The converter handles decimal inputs for precise measurements needed in baking, precious metals, and scientific applications.
Worked Examples
Baking Recipe Conversion
A French croissant recipe calls for 500 g flour, 250 g butter, and 30 g sugar. Converting to ounces: 500 / 28.35 = 17.64 oz flour (approximately 1 lb 1.6 oz), 250 / 28.35 = 8.82 oz butter (approximately 2 sticks plus 1 tablespoon), and 30 / 28.35 = 1.06 oz sugar (approximately 2 tablespoons).
Gold Weight Conversion
A gold chain weighs 15 grams. In troy ounces (used for precious metals): 15 / 31.1035 = 0.482 troy oz. In avoirdupois ounces: 15 / 28.3495 = 0.529 oz. If gold is priced at $2,000 per troy ounce, this chain contains approximately $964 worth of gold by weight. Always use troy ounces for precious metal calculations.
Nutrition Label Interpretation
A protein bar lists 20 g of protein, 15 g of fat, and 25 g of carbohydrates per 60 g serving. In ounces, the serving is 2.12 oz and contains 0.71 oz protein, 0.53 oz fat, and 0.88 oz carbs. These conversions help when comparing products labeled in different systems or calculating macros for dietary planning.

Practical Tips
- For cooking, remember that 1 ounce is approximately 28 grams. Round to 30 g for very quick mental math (accurate within 6%).
- Invest in a kitchen scale that switches between grams and ounces - it eliminates conversion errors entirely.
- For precious metals, always use troy ounces (31.1 g), not standard ounces (28.35 g). The difference is about 10%.
- Nutrition tracking is easier in grams because food databases worldwide standardize on metric measurements.
Key Takeaways
- 11 gram equals 0.035274 ounces, and 1 ounce equals 28.3495 grams.
- 2Cooking and baking are the most common uses for this conversion, where precision directly affects results.
