Ounce type:
Result100 g = 3.527 oz (Avoirdupois)
Quick answer
The ounce used for food and most goods is the avoirdupois ounce, which weighs 28.3495 g, so divide grams by 28.3495 to get ounces. That makes 100 g about 3.53 oz. Gold and silver are weighed in the heavier troy ounce (31.1035 g), so switch the toggle for those. These are ounces of weight, not the fluid ounce used for liquids.

Choose the right ounce. Food, mail and general goods use the avoirdupois ounce (28.3495 g); only precious metals use the troy ounce (31.1035 g). The toggle switches between them.

These are ounces of weight. If your grams describe a liquid you want in fluid ounces, that is a volume, handled by grams to mL and the fluid-ounce tools.
