鸡蛋2 个3 个
牛奶240 ml360 ml
糖60 g90 g
黄油50 g75 g

Calculation steps

  1. 1缩放系数 = 6 ÷ 4 = 1.500（约 ×1.5）
  2. 2面粉 = 600 g（原 400）
  3. 3鸡蛋 = 3 个（原 2）
  4. 4牛奶 = 360 ml（原 240）
  5. 5糖 = 90 g（原 60）

  • Weigh ingredients (g/ml) instead of using cups — scaling by weight is far more accurate.
  • Eggs: round to whole eggs; half an egg ≈ 25g beaten egg.
  • Spices & salt: scale at ~1.2× of the factor for ×1.5 scaling, then taste and adjust — they do not scale linearly.
  • Baking is chemistry: for cakes/bread scale everything precisely and keep the pan depth similar, or adjust bake time.
  • Cooking time barely changes with quantity; thickness and pan size matter much more.
