The question as posed is unanswerable. In order to compute the weight of an inch of water, one would have to know the volume, or area the one inch covers. (ie., a square foot of water one inch deep would weigh=X)
Normally you would not measure water per inch since the concept makes no sense.

Yes, 1/2 inch supply to fill boiler will work fine. Piping going to baseboard heaters needs to be sized properly. 1/2 inch piping to baseboard heaters not recommended. Most hot water baseboard heaters piped with 3/4 pipe.
That depends on the pressures you are running off the Engine and the G.P.M your achieving at the business end? Theoretically, you would need a 3 inch supply line too supplement two 1.5'' lines,You need to put in enough water supply to achieve the output of water, unless your utilizing tank water.
an eight of an inch is 3mm or 0.3cm
The cost would be whatever the price is per foot/inch.

Eight inches rounded to the nearest half inch is still eight inches.
