water). The results are usually expressed in grams/liter (g/l) or parts per thousand (ppt) for sea water (Pacific Ocean water are around 32 g/l in winter). In freshwater the term “total dissolved solids” (TDS) is often used for the same thing instead of “salinity”. Useful TDS units are milligrams/liter (mg/l) or parts per million (ppm).
