I scrap on a relatively small scale and had a thought/question about weights and scales. On occassion I find a small amout of copper wire and strip all that I find. When I weigh it on my bathroom scale which calibrates down to .1/lb I might get(for example) 5.8 lbs of copper. If I take that to the yard, on their scale which only calibrates to lb. it will weigh 5 lbs, because the scale rounds down. If thats the case I just lost .8 lbs. of copper. I realize that may sound cheap but do it enough times and it can add up. Any opinions?
