Dear Sir/Madam

I am having trouble establishing the units of integrated Pixel Density.
So far I have analysed an 8-bit image with subtracted background and has a threshold of 0-255 of silver stained rat brain tissue.
I know so far that pixel density is the sum of all the pixels in the given analysed area...
But what are the units? When you get results summary, you get at 0.8 or 0.988 or 0.33 or even 1.23 - but in what?

Many thanks,
Hazel May
