🔬 Why Do Cups to Grams Conversions Vary? (Click to learn)
The Simple Answer
Cups measure volume (space), while grams measure weight. Think of it like this: a cup of feathers weighs much less than a cup of rocks, even though they take up the same amount of space.
⚠️ Why This Matters
- • Cookies spread too thin? Not enough flour (under-measured)
- • Cake too dense? Too much flour (over-packed cups)
- • Frosting too sweet? Wrong sugar conversion used
