It just ranges better in my opinion. 70 degrees farenheit vs. 21.11 degrees Celsius

It’s been a while since I had to convert Kindle books, but the last time I did - Calibre was the way to go.

It’s a complete collection manager too so you can edit metadata, cover art, format and so much more.

It’s definitely intimidating when starting out, but well worth it.
