Everything else (temperature, atmospheric pressure, environment) being the same, the only factor you need to consider is the (relative) densities of H2O and Hg.
The density of water = 1 g.cm-3 at T=20oC and 1 standard atm.
The density of Hg = 13.5 g.cm-3.
Hence, the pressure for a column of H2O 40 cm high in vacuum is the same as that for a column made of 40 [cm] / 13.5 = 2.96 cm of liquid Hg in vacuum.
* Note that the atmospheric pressure is indicated by the height of the liquid in an inverted tube (open-end facing down) with a (partial) vacuum at the top of the tube.
