Cups measure volume — how much space something takes up. Grams measure weight. A cup of flour weighs much less than a cup of honey because honey is much denser.
Flour is the trickiest ingredient to measure by cup. If you scoop flour directly from the bag, you can pack in up to 50% more than if you spoon it lightly into the cup. This is why professional bakers always weigh flour in grams.
