It is the pressure exerted by a column of mercury 1 inch (25.4 mm) in height at the standard acceleration of gravity .
The density 13 595.1 kg/m 3 chosen for this definition is the approximate density of mercury at 0 °C (32 °F), and 9.806 65 m/s 2 is standard gravity. The use of an actual column of mercury to measure pressure normally requires correction for the density of mercury at the actual temperature and the sometimes significant variation of gravity ...
