Salinity is the measure of the amount of salt in the water and the units is parts per thousand (ppt). The salinity of seawater varies around the world, but on most Indo-Pacific reefs (including Australia) the salinity is around 35 ppt. This means that there is around 35 grams of dissolved salt in one kilogram of seawater. Notes that for scientific applications, the definition of salinity is somewhat more complex.
Salinity is typically approximated by measuring the specific gravity of the water.
