The degree of concentration of salt in the ocean water is called salinity. As a general way to record, the amount of salt in 1,000 g of water is taken as standard. Thus, salinity is expressed in terms of ‘parts per thousand’ (ppt).

The average salinity of oceans is about 35 ppt, whereas the dead sea has a salinity of 342 ppt.
