单位转换器页面服务于工程师、译员以及任何工作中涉及不同单位测量值的其它人士。

观看视频,学习科技英语!你可以使用本在线转换器76大类的数百个单位,几千个单位对。

这些类别包括加速度、面积、电气、能量、力、长度、光、重量、质量流量、密度、比容、功率、压力、应力、温度、时间、扭矩、速度、粘度、体积和容量、容积流量等。

注:整数(不带小数点或指数符号的数字)精确到15位数,而小数点后面最多保留10位数。

在此计算器中,符号E表示太小或太大的数字。

符号E是科学记数法a•10x的另一种格式。

例如:1,103,000=1.103•106=1.103E+6,这里E(指数)代表“•10^”,即“乘以10的次方”。

符号E常见于计算器中,使用人群为科学家、数学家以及工程师。

在左边的列表框内选择原单位。

在右边的列表框内选择目标单位。

在左边的由框内输入一个值(如“15”)。

转换结果就会出现在结果框内以及至框内。

或者,你也可以在右边的至框内输入该值,然后读取由框内以及结果框内的转换结果。
