WebSalinity Conversion Calculator This calculator converts between various units of salinity. In 1978, the Practical Salinity Scale (PSS-78) was adopted, which yields a practical salinity from equations, smooth expansions of conductivity ratio, which were carefully fit to the real salinity of diluted North Atlantic seawater. The numeric unit from PSS-78 is psu (practical salinity unit). In soil salinity measurements we use the saturation paste extract to get the pore water extract and then use a electrical conductivity meter to det This article presents a simplified conversion to salinity units for use with specific conductance data from monitoring stations that have been normalized to Salinity - .
