Ounces to Grams Converter

Convert ounces to grams and grams to ounces. 1 oz = 28.35 g exactly. For dry ingredients and liquids alike — weight is weight.

8 oz in grams

226.8 g — 0.5 lb

1 oz = 28.35 g exactly. 8 oz = 226.8 g.

Weight ounces only — fluid ounces (fl oz) are a volume. For liquids by volume, use the liquid volume converter.

Formula used: 1 avoirdupois ounce = 28.3495 g exactly. Grams = ounces × 28.3495; ounces = grams ÷ 28.3495.


How the ounces-to-grams converter works

One avoirdupois ounce is exactly 28.3495 g. The tool converts both ways, so 8 oz is 227 g (half a pound — the weight of one cup of butter) and 100 g is 3.53 oz. Weight is weight: this conversion is exact, not an estimate.

Watch out for

Do not confuse weight ounces with fluid ounces. A fluid ounce is a volume (29.6 ml) and only equals a weight ounce for water. 8 fl oz of honey weighs about 11 oz, not 8. If your recipe says "fl oz", use the liquid volume converter instead.
