I'm kinda beginner, was reading a lot of stuff here but seems language barrier is too strong so i'm about to give up.

First, i'm not a premium member, so i want to be sure am i would be able to calculate this thing like that or not?

Back to the point, i'm have a pretty good aim and so the muscle memory with BF 4 hip and ads with "usa" and "fov scaling ads" on. I converted hipfire pretty allright but have no idea how to convert ads.

As i understand, the deafailt 133 usa from BF4 can be converted and the result would fit for all players, no matter the base sense. If that is correct does someone calculated it allready? Ans if ads should be calculated around base sense can someone help me with that?

My BF4 conf
  hip - 0.014199, usa - on (default 133), fov scaling ads - on

You can only convert one of the zooms /scopes in Apex unless you use BF USA 0%, since that's the setup Apex uses, and the game only has one master ADS slider that affects all scopes together (at the moment anyway)

You'd set up the calculator like this (this assumes 400 dpi, and 74 vertical FOV, to convert to Apex hipfire and to the SMG scopes - you'd have to enter whatever those are yourself since you didn't say what you use)
