Variable Weight of Same item?

Would it be possible to store inventory for same item with different weights as after production weights varies and price depends on weight.
For example... If i am entering work order for item A and after producction, i am getting 50 units of item A and each unit has variable weight like
Item A 1st unit = 2.5664 kg
Item A 2nd unit = 2.6654 kg
Item A 3rd Unit = 2.8456 kg and so on...
and price depends on individual weights......
Please help me.............Thanx..............

This is precisely the reason for Dual Unit of Measure items. Look that topic up in the E1 manuals. It utilizes the Primary and Secondary UOMs in the setup.
