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.

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
