[Histonet] NIH image J surface area unit

[Subratab]

Dear Histo experts
My friend is measuring glomerular surface area by using Image J software. He
is in trouble to get the unit of the area calculated by the software, I
mean, if the calculated area is to be expressed in square milimeter or
square micrometer.
He is capturing the figures from microscope with X100 magnification
(oil-emersion lense) and then analyzing the glomerular surface area by the
software in a computer.
Could anybody please help to solve this.
Sincerely
