What is Unit Converter?单位换算 是什么？

A unit converter translates a value between length, weight, temperature, area, volume, speed, time and data units. It handles the awkward cases correctly — Fahrenheit to Celsius uses the offset formula rather than a simple ratio, and data units are converted with both the decimal (KB = 1000 B) and binary (KiB = 1024 B) conventions. All conversion runs offline in your browser.

单位换算器在长度、重量、温度、面积、体积、速度、时间和数据单位之间转换数值。它正确处理特殊情况——华氏与摄氏使用偏移公式而非简单比例，数据单位同时提供十进制（KB=1000B）和二进制（KiB=1024B）两种约定。全部换算在浏览器离线完成。
