Sorry, but any of the suggestions on how to do a conversion should be ignored. Most KF8 (AZW3) eBooks started life as ePub. So the best way to go from KF8 > ePub is to install the KindleUnpack plugin and shift the KF8 > ePub and then use Calibre's eBook editor to edit what needs to be fixed such as rem in the CSS instead of em and there are a few simple things in the OPF that will need to be fixed. Also make sure you have the epubcheck plugin for the editor installed so you can use that to validate the ePub. This will get you the code as it is instead of as it will be after a conversion. Yes, the filenames are a mess, but that's how they would be after a conversion. A shift is the best way to convert.
