This calculator calculates for concentration or density values that are between those given in the table below by a
process called interpolation. Input a temperature and density within the range of the table to calculate for
concentration or input concentration to calculate for density. The table below gives the density (kg/L) and the corresponding
concentration (% weight) of Sodium Hydroxide in water at different temperatures in degrees centigrade (°C).
The table was taken from "Perry's Chemical Engineers' Handbook" by Robert H. Perry, Don Green, Sixth Edition.
