Common mistakes
- Cups measure volume and grams measure weight. Converting between them depends on the ingredient: a cup of flour weighs roughly 120–130 g, a cup of sugar about 200 g.
- Cup sizes vary: US customary 236.6 mL, US nutrition label 240 mL, metric (Australia, Canada, UK recipes) 250 mL.
- An Australian tablespoon is 20 mL (four teaspoons), not 15 mL.
