*milligrams per liter (mg/l) may be converted to parts by million (ppm) by dividing mg/l by the spacefic gravity times 10,000.
The relationship between mg/l sodium chloride and mg/l chloride is shown as follows:
mg/l Sodium Chloride = mg/l Chloride x 1.649
mg/l Chloride =mg/l Sodium Chloride x 0.6066
