Inductance Converter
Inductance measures how strongly a coil opposes a change in current by storing energy in a magnetic field. The SI unit is the henry. Power-supply chokes are rated in millihenries, RF coils in microhenries and nanohenries, and transformer windings can reach whole henries.
20 units supported Base unit henry (H)
