I'm currently calculate the solubility parameter using the scripts file provide by CERIUS. The script file calculated the cohesive density energy and solubility parameter. As I know the solubility parameter (delta) have different unit: (MPa)1/2 or (J/cm3)1/2 or (cal/cm3)1/2. In the scripts file, they defined that: (cal/cm3)1/2 = 2.0455 (J/cm3)1/2. However, when I search the internet, it appearred that: (J/cm3)1/2 = 2.0455 (cal/cm3)1/2 and (MPa)1/2 = 2.0455 (cal/cm3)1/2 I have no idea who are right here. I mean the scripts file is provided by CERIUS. Thank you very much for your help. LH Aaron Deskins wrote: Summary: I'm looking for a review of term symbols- particularly molecular.

Hi CCL,
   Could someone please help me with the problem that I have right now with the unit of the solubility parameter.
    I'm currently calculate the solubility parameter using the scripts file provide by CERIUS.  The script file calculated the cohesive density energy and solubility parameter.   As I know the solubility parameter (delta) have different unit: (MPa)1/2 or (J/cm3)1/2 or (cal/cm3)1/2. 
In the scripts file, they defined that:
     (cal/cm3)1/2 = 2.0455 (J/cm3)1/2.
However, when I search the internet, it appearred that:
    (J/cm3)1/2 = 2.0455 (cal/cm3)1/2    
and
    (MPa)1/2 = 2.0455 (cal/cm3)1/2
 
I have no idea who are right here.  I mean the scripts file is provided by CERIUS.
 
Thank you very much for your help.
