Hello. Great day!

I would like to know wich unit represents the result of VSG_Strain. For example pixels, mm, etc

Typically, the units for strain are mm/mm, which some refer to as having a unit of one. The same is true for the VSG_Strain. It's not really tied to the calibration (or the conversion of pixels to mm) since it's unit length per unit length. For your purposes you can consider the VSG_Strain units as pixel/pixel or mm/mm. Hope that helps.
