Hi Ben,

each ImagePlus [1] has a method called ``getCalibration()``. It returns
the Calibration [2] instance of the ImagePlus. The Calibration Object
contains all the methods you need. ``getUnit()`` returns a String to
check if the unit is µm. ``getX(double x)`` converts a pixel value into
a physical unit.

Best regards
Michael
