Coil32 is an inductance coil calculator that allows to calculate the single-layer and multi-layer air core inductors, the ferrite toroid inductors or chokes, flat square coils on PCB etc.

The app allows calculating the needed number of turns for the desired value of inductance of a homebrew inductor or to calculate the inductance value of a fabricated inductor. I hope this app could be useful for HAMs, Audiophiles and other radio enthusiasts who need to make DIY inductors.
I need for help from native speakers to translate this app in Indonesian etc. If you can give me the help, please email me.
