The conversion from cups to grams is not a fixed ratio — it depends entirely on what you're measuring. A cup is a unit of volume (how much space something takes up), while grams measure weight (how heavy it is). Since different ingredients have different densities, the same volume produces different weights.
This is especially important for baking, where precision matters. Professional bakers almost always weigh their ingredients in grams rather than using volume measurements. If you're following a recipe from another country, you'll often need to convert between these systems.
