Option #2 is the correct one (2.87 lbs), see my post above. I think the confusion comes in when cans of refrigerant are sometimes called a "pound" when in fact they only contain 10, 12, or 14 oz. of refrigerant. Also, in your search on this forum, you may run into calculated capacities of R134a, which are around 80% of R12 capacity in a converted system (could be your option #4).
