Fluid ounces vs ounces by weight

US recipes use "ounces" for both. Liquids are usually fluid ounces (a measuring jug), while cheese, chocolate or flour sold by weight are ounces on a scale. One fluid ounce of water weighs 1.04 oz, so for water the two are close, but a fluid ounce of honey weighs 1.49 oz. Switch the converter to "Ounces (weight)" and pick the ingredient to convert weight ounces.
