Fluid ounces vs weight ounces
Fluid ounces (fl oz) measure volume, how much space something takes up. Ounces (oz) measure weight, how heavy it is. For water, 1 fluid ounce weighs about 1 ounce; for flour, sugar or oil the two differ, so check which one a recipe means. For weight, use ounces to grams.
