The conductivity of water is measured in Siemens per meter (S/m). Sea-water is typically 5 S/m, [5] drinking water is typically in the range of 5-50 mS/m, while highly purified water can be as low as 5.5 μS/m (0.055 μS/cm), a ratio of about 1,000,000:1,000:1. Purified water is used in the pharmaceutical industry.
