Since Russian standards differ substantially from nato ones you cannot compare claimed protection/penetration stats directly, Though this has not stopped morons on the internet from doing it anyway.

I have come across a few claims that Russian/Soviet methods of calculating armor penetration would be of higher standards than the ones used by foreign armies But I am not good when it comes to finding reliable sources so I need some help.

Could anyone help me try and come up with a formula to help translate the an armor penetration value between standards?
