WebOct 14, 2012 · PPM = parts per million Std Dev = standard deviation; a sigma node; (Greek letter symbol “∑”) UL = upper limit, using 3 times the sigma UOA = used oil analysis The wear elements are listed as seen in the periodic table of elements: Al = aluminum Cr = chromium Cu = copper Fe = iron Pb = lead ( note : all wear metal data is reported in ppm) Webgpg = ppm/17.118. In essence, if you divide parts per million by 17.118, you get grains per gallon. Factor 17.118 comes from the volumetric and mass difference between the water hardness units. Thus every 1 gpg is equal to 17.118 ppm (1 gpg = 17.118 ppm). Water hardness calculations are most relevant for water softener systems.
