SSS input values

I have posted, under a different user name, on Blender Artists and cgtalk asking what the SSS input values relate to. I am curious about the measure.

Scale makes sense to me as it is explained in the wiki as does the color, front and back inputs. Those are percentages.

Radius is perhaps my biggest hang up. The wiki explains the radius as an average distance. How is that distance measured? Is it BU? Is it BU effected by the scale value? Or is it something else?

I would just like to better understand how SSS works through better understanding of the input values.
