About converting grams to ounces
Grams to ounces bridges metric recipes and product weights into the ounce-based measurements common in US kitchens and on imperial scales.
One ounce is about 28.3495 grams, so to convert grams to ounces you divide by 28.3495. A 100 g portion is 3.53 oz, a 250 g block of butter is 8.82 oz, and a 500 g package is 17.64 oz.
This is the avoirdupois ounce used for everyday weight — distinct from the troy ounce (about 31.1 g) used for precious metals, and from the fluid ounce, which measures volume rather than weight. For cooking and groceries, the 28.35 g ounce is the one you want.
- Rough estimate: divide grams by 28, or by 30 for an even faster ballpark.
- Don't confuse weight ounces with fluid ounces — they only coincide for water by rough luck, not by definition.
