原理 / 公式来源

质量换算是线性比例关系。SI 以千克（kg）为基本单位；克（g）、毫克（mg）等是十进制分量。磅（lb）、盎司（oz）等与 kg 的关系由国际约定确定，因此因子固定。

本工具统一换算到 kg：目标 = 源 ×（源→kg）÷（目标→kg）。对 u 等科研单位，因子来自权威常数推荐值。

公式与示例

公式：目标值 = 源值 × (源→kg) ÷ (目标→kg)。

示例：5 lb ≈ 2.26796 kg；250 g = 0.25 kg。

常见误差 / 注意事项

质量（kg）不等于力（N）；重量应使用力换算并考虑重力加速度。
注意前缀：mg、g、kg 相差 10³，最易误读。
极小数值建议提高显示精度，避免看不出差别。

实际应用场景

在实验配制、运输和包装中很常见，标签常在 kg、g、lb、oz 间切换。

科研报告中建议统一质量单位，保证密度/浓度等派生量一致。
