Common Mistakes When Converting Cups to Grams
Using a “one size fits all” rule
Flour, sugar, and butter all weigh differently. 1 cup ≠ same grams for all.
Takeaway: Use ingredient-specific values.
Not leveling flour
Scooping flour packs it in. Level with a knife for accuracy.
Takeaway: Spoon and level flour into cups.
Ignoring recipe region
U.S. cups differ from metric cups (240 vs. 250 mL). This impacts grams too.
Takeaway: Check which cup size the recipe uses.
