Cartridge Compliance

As a layman I need some basic help with determining the compliance of a cartridge. If the manufacture identifies compliance at 100Hz as 7×10-6cm/dyne how do you convert that to a compliance number similar to 16 µm/mN. Also what numbers would indicate high, medium and low compliance. I have review the forum and found a lot of info on compliance but not the answer to these questions. Thanks for your help
