You should never compare the zoom powers between games. In most cases there is absolutely nothing similar between them, it's just an arbitrary number slapped onto an aim by the devs.
The only thing you should be paying attention to is the scope's real FOV, which you can see in the output of the calculator.
Either way though, you can use the calculator to replicate the scope scaling from i.e. Apex to other games. Just share an entry with your Apex settings and I can help you. Or if you don't know, just share all your config file settings, and I can set it up for you.
