I was looking for a uniform sensitivity I can use so that the sensitivity I would have the same sensitivity in game as I do while generally using my pc ( Surfing the web, editing, coding, etc). So my mouse sensitivity is at 800 dpi with pointer speed being 6/11. But then I found something strange:

 

With the increase the in game FOV from 80 to 103 there was an increase in sensitivity which does not make sense because I am under the impression that an increase in FOV would reduce the number of pixels the mouse would need to travel and therefore proportionally decrease the mouse sensitivity  ( I could be wrong about this). 

 

 

If I am doing this wrong could you please tell me how I could do this correctly ?

If I am doing this wrong could you please tell me how I could do this correctly so that my desktop sensitivity would be the same the in game sensitivity

Remember that the pixels refer to the physical pixels on your monitor, so they never change. At FOV 80 each pixels covers less FOV than at 103, so if you want to move one pixel, you have to move further at 80 (assuming the 360 distance does not change with FOV). 

ok I understand so how do I go about making sure my desktop sensitivity is the same as my in game sensitivity because I have tried with this with different games and they all feel wildly different and don't feel like my desktop sensitivity at all.

What you have done is correct, but one caveat of this conversion is that the sensitivity changes a lot with the FOV. So you will not get any consistency in terms of 360 distance for hipfire, but the pixel ratio will stay the same (this is essentially MDV 0%).

The difference between FOV 103 and 80 is basically the same difference as hipfire and ADS in many games, so preserving the tracking speed rather than 360 might make sense in that context. But if you prefer the same 360 distance for hipfire, my advice is to convert from desktop to hipfire for a "normal" FOV like 103, then use the result of this (i.e. the Overwatch sensitivity) as the base for your other conversions and set the hipfire conversion to 360 distance.
