Sea Water Density at Various Temperatures 
The purpose of this graph is to provide the density of sea water at any temperature apt to be encountered when 
the density at the standard temperature of 59°F (15°C) is known. To convert a density at 59°F (15°C) to density 
at another temperature, enter the graph horizontally from the left with the known density and downward from 
the top or upward from the bottom with the desired temperature; the position of the point of intersection with 
respect to the curves gives the density at the desired temperature. Interpolate between curves when necessary. 
For example, by this method, water having a density of 1.0162 at 59°F is found to have a density of 1.0124 at 
85°F. The densities are referred to the density of fresh water at 4°C (39.2°F) as unity.
