To convert ounces to grams, you multiply the number of ounces by the conversion factor. For standard (avoirdupois) ounces, the factor is 28.3495231. For example, 5 oz × 28.3495231 = 141.75 grams.
No, 1 standard ounce is exactly 28.3495231 grams. While 28 grams is often used as a rough estimate in everyday cooking, precise baking or scientific measurements require the exact decimal value.
A standard (avoirdupois) ounce is used for everyday weight measurements and equals 28.35 grams. A troy ounce is used exclusively for weighing precious metals like gold, silver, and platinum, and is heavier, equaling 31.10 grams.
A fluid ounce (fl oz) measures volume, not weight. However, for water at standard temperature, 1 fluid ounce weighs approximately 29.57 grams. The weight of other liquids will vary based on their density.
Recipes in the US and UK traditionally use ounces (volume or weight) due to the imperial system. However, professional bakers globally prefer grams because weighing dry ingredients in grams is significantly more accurate and consistent than measuring by volume.
