what's the relation between a resolution and the size of pixel?

Hello, An image with a resolution of 0.254 mm * 0.254 mm means that a pixel size is 0.254 mm??? thanks

Sounds like it. Resolution is how many pixels per unit linear measure, so in the U.S. we would say
1/pixelsize = 1/(.254) = 1/(.01) = 100 pixels per inch (ppi)
ImageAnalyst will correct me if I am wrong, but I think this is how it works.

It's possible to have more pixels than your actual spatial resolution if your image is blurry. Plus it depends on how you define resolution. Some people say you need at least a pair of pixels to resolve two things that are located side by side. One pixel has one object, then a blank pixel for the second pixel, then the other object at the next (third) pixel.

25.4 mm/inch / 0.254 mm/pixels = 100 pixels/inch

You need to have the conversion factor in there too, Pamela:
(1pix/.254mm) * (25.4mm/inch) = 100 pix/inch
