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.

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