  "term": "Practical salinity units",
  "field": "Meteorology and atmospheric science",
  "definition": "A dimensionless unit used to express the salinity of seawater, based on the electrical conductivity ratio of a seawater sample to a standard potassium chloride solution. This scale replaced older methods based on chlorinity and is widely used in oceanography and marine meteorology. A value of 35 PSU corresponds approximately to 35 grams of dissolved salts per kilogram of seawater.",
