Hi Urvish,
The background information you need can be found here:

I sent you a link on a previous post that demonstrated the code used based on complete reference design. The information about the ADS1230REF can be found here:

The ADS1230REF user's guide explains the calculations required to convert a voltage to weight, and can be found on the above link.
Best regards,
Bob B
