本烘焙计算器的换算原理
量杯到克的每次换算均基于实验室测试的堆积密度，而非死板的单一容积假设。由于松散的面粉、结晶的砂糖和液体乳制品在物理密度上差异巨大，仅靠体积无法保证烘焙的成功率。本计算器采用严谨的物理密度公式：
换算范例：如果您的配方需要2.5美制量杯通用面粉，计算器将2.5乘以标准密度120克/杯：

烘焙精准称量技巧
烘焙是一门精密科学。量杯的舀取手法或食材温度的细微变化，都会直接影响面团筋度、蛋糕蓬松度与曲奇延展性：
优先使用厨房电子秤
精度达到1克的电子秤可彻底杜绝容积测量的误差。量杯受沉降松紧与环境湿度的影响极大。直接将搅拌碗置于秤上称量既精准又减少清洗工作。
勺舀刮平法 vs 量杯直接深挖
传统烘焙配方均默认采用“勺舀刮平法 (Spoon and Level)”：先用蛋抽将面粉搅松，用勺子轻轻盛入量杯中（切勿按压），最后用直刀平整刮去顶部多余部分。这样称出正好是120克/美制杯。
反之，若直接拿量杯插入面粉袋中舀取（Dip and Sweep），面粉会被紧紧压实，每杯重量高达130至140克（若压实更可达170克）。这多出的10%至40%多余面粉会吸收过多水分，导致蛋糕干硬、面包发死。

食材回温至室温的必要性
除非制作开酥千层需要冷硬黄油，否则黄油、鸡蛋和牛奶均需恢复至室温（18°C至21°C）。软化黄油与砂糖能充分打发并锁入微小气泡；冰冷的鸡蛋液则容易导致油水分离。
风炉与平炉烘烤温度换算
带热风循环的风炉升温和热传导比传统平炉更强烈。在使用风炉烘烤时，请将设定温度下调15°C左右，以防止蛋糕表皮过早焦化而内部尚未熟透。
