A lot of games have terrible sensitivity sliders and options.  Mouse software allows for and remembers custom dpi settings for games.  It would be easier for and more precise for me to convert by dpi instead of sensitivity in some games.  Would it be possible to have this feature? or does it already exist?

It does

Select Advanced Mode

And the output will show you the DPI for a perfect match, as well as the multiplier you need to apply to you current DPI:

 

That is close to what I was thinking about but it doesn't work if the game I'm converting to doesn't have the sensitivity range to support the dpi I'm converting from.  I just get no result saying the converted sensitivity is too low or too high.  I was thinking I could choose the in game sensitivity on the game I'm converting to and the calculator gives me a new DPI to match the game I'm converting from.  Or maybe if the sensitivity is outside the range it gives the max or min sensitivity and the DPI to match.

You should also get a new recommended DPI to get the sensitivity in range:

If you then enter this DPI for the game, you will get a valid calculation.
