They are the same, but most games do not use this scale.
What you want to do is convert directly from ADS to ADS. First convert hipfire to hipfire to get the base sensitivity (this is just an example, adjust your values according to your settings):
Then convert from ADS to ADS using the calculated hipfire sensitivity:
As you can see in this case you will get 0.65 in both games.
For PUBG it would be like this:
And for BFV like this (will also work with 0.65/65 if you set USA to 0) Zoom sens is 104% because of lack of decimals for hipfire.:
No, this method does not work for Apex, but it does work for some games.
