A month after the original posting the poster is probably long gone. Even if you want to argue the difference between weight and volume, you're only talking about a 6% difference. Even a corrected value at .245% is going to be within the HIGHEST range in PA (which is only .16) given your most favorable conditions. In practice, there is no discrpancy. The test and standard in PA (and just about everywhere in the US) is g/ml (i.e. per volume).
