亨利 (单位) Henry (unit)
（重定向自Femtohenry）
亨利（Henry），符号表示为H，是电感的国际单位制导出单位。如果电路中电流每秒变化1安培，则会产生1伏特的感应电动势，此时电路的电感定义为1亨利。
亨利在国际单位制中的量纲是V·A·s = m²·kg·s·A。
此单位是以美国科学家约瑟·亨利的名字命名的。

The henry (symbol H) is the unit of electrical inductance in the International System of Units. The unit is named after Joseph Henry (1797–1878), the American scientist who discovered electromagnetic induction independently of and at about the same time as Michael Faraday (1791–1867) in England. The magnetic permeability of vacuum is 4π×10 H m (henry per metre).
