The E0S80 is valid for S = 0 to 42; t = -2 to 40℃; p = 0 to 10000 decibars.

The following values are provided (Unesco Report No.38 p.191) for checking the correct use of the above equation. The density anomaly can be compared directly with p (S, t, p) when 1000. kg/m3 is added. Differences in the last decimal place particularly of specific volume can be expected due to round-off. (Units of p are kg m-3 and V m3/kg.)
