The results of 22 drill core samples from the hole BSH16-01 indicate maximum values for lithium of 270 parts per million (ppm), boron 410 ppm, potassium 10,000 ppm, and magnesium 12,000 ppm; and Convert ppm to percent or percent to ppm: This article describes the simple math used to convert between parts per million (PPM) and percentage, such as how we convert a measurement of 800 ppm of CO 2 in air (indicated on our colorimetric gas measurement tube shown at page top) and a percentage concentration of that same gas in air. Divide the ppm hardness value by 17.1, the conversion factor for ppm to gpg. The result is the water hardness expressed in grains per gallon.
