About Unit Converter
Last updated: May 2026
OptiPix 单位转换器可处理 10 个类别、100 多个单位的转换。转换长度（毫米到英里）、重量（克到磅）、温度（摄氏度到华氏度到开尔文）、面积、体积、速度、数字数据（KB 到 TB，二进制和十进制）、时间、压力和能量。键入时进行双向实时转换。每次转换都会显示所使用的公式。快速交换按钮可反转从/到单位。所有计算均使用纯 JavaScript 算术，无需外部依赖或网络调用。
How It Works
每个单位都存储一个相对于其类别中基本单位的转换因子（例如，长度的米）。要进行转换，该工具会将输入乘以源因子，然后除以目标因子。由于温度不是简单的比例关系，因此它使用特殊的公式。
Use Cases
- •在公制和英制测量单位之间进行转换
- •计算烹饪或天气的温度转换
- •转换数字存储单位以进行文件管理
- •转换时区和持续时间单位
- •计算建筑项目的面积和体积
