Table 1: Concentration of dissolved oxygen (mg/L) in water at various temperatures
and pressures
From R. F. Weiss (1970). Temp ° C, temperature in degrees Celsius;
atmospheric pressures from 695-600 millimeters mercury (27.36-23.62 “Hg) begin after 40° C
Conversion Factors: 1.0 “Hg = 25.4 mmHg = 33.86 mb or hPa
Temp.
