You have to use either a box or a BX to EMT conector like this
http://www.usahardware.com/inet/shop/item/30130/icn/20-067256/halex/15305b.htm and skin the metal cladding off AC90.None of the cladding can enter the pipe and there has to be a strain relief and of course anti-short.
I've also seen a bx connector to nipple to EMT box connector used to make the transition.
