Can you measure Part A and Part B tabletop epoxy by weight?

A  and  B  differ in weight. It would not be accurate. It's much more. 
 
consistent and less likely to have curing problems if it's measured by 
 
Volume than by weight. All epoxies have different methods to apply 
 
them, but if you want to get optimum use out of our product, we 
 
advise measuring by volume.
