Convert all math formulas to images

Hello,
I have many technical ebooks (epub, mobi) containing many math formulas.
In calibre for mac I can mostly read these formula correctly but when I transfer this same file (same format, already converted) to my kindle paperwhite (1st gen) many formula are not correctly rendered.

I'm quite sure this is a limitation of my kindle version, so nothing to be done there, I guess.

I was wondering if does it exist a converting procedure or a plugin that could convert all the math formulas into images in order to be correctly visualized in the reader.

Thanks in advance
