Changing DPI to match change in Windows Sensitivity

[Vendor]

I have 2 different questions that I hope you smart fellas can help me with. 

First. I play at 3250dpi (don't ask) and windows sens 4. I would like to play at windows sens 6 but  still match my current sens. I'm not sure how to convert this. 

 

Alternatively, second question, which may be more difficult to answer is I'd like to play at a more traditional sensitivity like 800 DPI. Some games don't give me the option of even going low enough in-game sens at my current 3250/4. I would have much less problems overall if I had 800 DPI. How could I match my perceived sensitivity at 800 DPI? Is there a calculation for that? Sorry is this is an ignorant question. I've been thinking about trying to do this for years. Now it seems there's a place I can ask at least.

Thanks.

A lot of games use raw input by default and ignores the windows sens. But if you want to convert, simply use the calculator and enter 3250 DPI and windows sens 4 (if it's grayed out the game uses raw input) for the input game, then select the same game as output game and set windows sens to 6. Alternatively set DPI to 800 for the output game if that's what you want to try. The calculator will tell you if the calculated sensitivity is out of range.
