Unit Converter

功能说明What It Does

单位换算工具支持长度、重量、温度、体积、面积、速度、数据存储与时间八大类别，覆盖公制与英美制常用单位，输入数值即可实时得到同类全部单位的换算结果。

The unit converter covers eight categories — length, weight, temperature, volume, area, speed, data and time — with the metric and imperial / US units you use most, showing every unit in a category the moment you type a value.

例如英寸转厘米、英尺转米、磅转千克、华氏度转摄氏度、加仑转升等，都可以秒级完成。

Convert inches to cm, feet to meters, pounds to kg, Fahrenheit to Celsius, gallons to liters and more in an instant.

所有计算都在浏览器本地完成，无需上传任何数据。

Every calculation runs locally in your browser — nothing is uploaded.

适用人群Who Should Use

赴美留学、旅行或跨境电商的用户，需要快速换算英制与公制单位。

Students, travelers and cross-border shoppers who need to switch between imperial and metric units quickly.

厨师、健身爱好者、工程师与学生，用于烹饪、健身、测量与作业换算。

Cooks, fitness enthusiasts, engineers and students for recipes, workouts, measurements and homework.

技术原理How It Works

每个类别定义一个基准单位，各单位通过精确换算因子映射到基准单位，温度额外处理偏移量，从而保证精度。

Each category defines a base unit, and every unit maps to it via a precise conversion factor; temperature also applies an offset for exactness.

数据存储类别同时提供十进制（KB/MB/GB）与二进制（KiB/MiB/GiB）单位。

The data category offers both decimal (KB/MB/GB) and binary (KiB/MiB/GiB) units.
