How to maintain Unit of Measure and Estimated weight information on physical product?

Hello,

 

We have below attributes from classic engineering central which needs to be carry forwarded to UPS model:

  1. Unit of Measure
  2. Estimated Weight

 

Any suggestions on how do we maintain these information on the physical products? These are not OOTB attributes on physical product. 

 

Any feedback / suggestion is very much appreciated.

 

Regards,

Sayoni Gotmare
