What is Ounces to Grams Conversion?
Ounces to grams conversion transforms imperial mass measurements into the metric system. The ounce (oz) is a unit of mass in the imperial system, defined as exactly 1/16 of an avoirdupois pound. The gram is one thousandth of a kilogram, the base SI unit of mass. One avoirdupois ounce equals exactly 28.349523125 grams. This conversion is among the most commonly needed in cooking, baking, nutrition, and international commerce, where products and recipes frequently use different measurement systems.
The Conversion Formula
The formula is: grams = ounces x 28.3495. For quick mental math, multiply by 28 for a rough estimate. For example, 4 ounces x 28 = 112 grams (exact is 113.4 grams). For better accuracy, multiply by 28.35. Common cooking equivalents worth memorizing: 1 oz = 28 g, 4 oz = 113 g (a quarter pound), 8 oz = 227 g (half a pound), and 16 oz = 454 g (one pound). These anchor points make it easy to estimate without a calculator.
Common Use Cases

- Comparing US food labels (ounces) with international labels (grams)
- Postal and shipping weight calculations for international packages
- Jewelry making and precious metal measurements
- Pharmaceutical applications requiring precise gram measurements
- Specialty coffee and tea preparation (precise gram measurements improve consistency)
Ounces in Cooking and Baking
In cooking and baking, the distinction between weight ounces and fluid ounces is critical. Weight ounces (oz) measure mass and convert to grams, while fluid ounces (fl oz) measure volume and convert to milliliters (1 fl oz = approximately 29.57 mL). Water happens to weigh roughly 1 oz per fluid ounce, but this relationship does not hold for other ingredients. Flour, sugar, butter, and chocolate all have different densities, so 8 fluid ounces (1 cup) of flour weighs about 4.25 ounces (120 grams), not 8 ounces. Professional bakers and pastry chefs prefer weight measurements in grams because they are more precise and consistent than volume measurements. When converting American recipes, always check whether the recipe specifies weight ounces or fluid ounces.
