<div>
<pre>When running mouse-dpi-tool /dev/... it says:
If your resolution is not in the list, calculate it with:
resolution=xxxxxx/inches, or
resolution=xxxxxx/(mm * 25.4)
The last line, the operation to convert mm to inches is wrong, you always have
more mm than inches, so you divide to convert. The correct formula is:
resolution=xxxxxx/(mm / 25.4)
or:
resolution=xxxxxx / mm * 25.4
or, my preferred:
resolution=xxxxxx * 25.4 / mm</pre>
