FAQ
Is data size based on 1024 or 1000?

示例与注意事项Example & notes
一个例子A worked example
做菜看到食谱写 1 lb 牛肉：输入 1，选「磅 → 克」，得到约 453.6 克；长度、面积、体积、速度与数据单位同样一键换算。A recipe says 1 lb of beef: enter 1, choose pound → gram, and get about 453.6 g. Length, area, volume, speed and data units work the same way.
注意事项Things to watch
- 市制单位（里、斤、亩）各地口径略有差异，本站按常用标准换算。Chinese traditional units (li, jin, mu) vary by region; we use the commonly accepted standard.
- 温度换算是带偏移的线性运算，不能只乘系数（0℃ 不等于 0℉）。Temperature conversion involves an offset, not just a multiplier — 0 °C is not 0 °F.
- 数据单位同时给出 1000 进制（KB/MB）与 1024 进制（KiB/MiB）两个结果。Data units are shown in both decimal (KB/MB) and binary (KiB/MiB) conventions.
相关问答More Q&A
为什么 1 GB 会出现两个数字？Why do I see two numbers for 1 GB?
因为存在 1000 进制与 1024 进制两种口径：硬盘厂常用前者，操作系统常用后者，我们把两个都列出来避免误解。Because two conventions exist: storage vendors use 1000-based units, operating systems use 1024-based ones. Both are listed to avoid confusion.
换算结果能直接复制吗？Can I copy the result?
可以，点结果右侧的复制按钮即可，复制的是纯数字便于继续计算。Yes — use the copy button next to the result; it copies the plain number so you can keep calculating.
