If you want to convert DMG to ISO, it's good to learn a little about disk image file types and what they're meant for. Essentially, a disk image is a snapshot of the content on a DVD, CD, BRD or even a hard drive. It could be just a set of media files, but it can also contain software installation files. In the second case, the disk image will also need to contain boot information in order to boot from the media.

At times, you may need to convert DMG to ISO so you can mount it as a virtual drive on a Windows machine to extract the contents, view them or burn them to create bootable media.
