Is there a measurement scale for stickiness?

The technical term would be "tack" or "tackiness".

Measurement is force per unit area, in case of tensile tack.

Generally used with viscoelastic materials, whose properties are often affected by shear rate.  So, tack can depend on the properties of the substrate(s), the adhesive(s), geometry, and the rate at which they are pulled apart.
