Hi Carl,

If you do it much there is a plugin  "Microscope Scale" 
http://rsb.info.nih.gov/ij/plugins/microscope-scale.html
that can be edited with the values you get for your system so that you 
have them conveniently available. If you work with several systems with 
different calibrations that is easy also - check the info on my webpage 
on how to set this up - includes a detailed "HOWTO", etc:
Image Calibrations with ImageJ - 
http://www.bio.umass.edu/microscopy/resource.htm
http://www.bio.umass.edu/microscopy/Downloads/Calibrations_HOWTO.html

This is entirely a functional adaptation of the Microscope scale plugin 
to illustrate how to have multiple calibrations available from different 
systems.

Hope this helps.

Dale
