Ounces to Grams

Convert ounces to grams for any cooking ingredient. Quick reference chart: 1 oz = 28.35g.

One ounce equals exactly 28.3495 grams — a fixed conversion that never changes regardless of the ingredient. Unlike cups-to-grams (which depends on density), ounces already measure weight, so the math is always the same: multiply ounces by 28.35.

American recipes frequently use ounces (oz) for both weight and volume — be careful not to confuse weight ounces (oz) with fluid ounces (fl oz). The pages below deal with weight ounces only. For ingredient-specific charts showing how ounces compare to cups and grams, select an ingredient.

1 oz = 28.3g · 2 oz = 56.7g · 4 oz = 113.4g · 8 oz = 226.8g · 16 oz = 453.6g
