You probably should not do so.

Explanation:

#"Torr"# or #"mm Hg"# are a very convenient measurement to use ON EARTH. #1# #"atmosphere"# of pressure will support a column of mercury #"760 mm"# high. This is a very visual and very convenient way to measure atmospheric pressure in a laboratory. Of course on Venus (which has a much thicker atmosphere), the atmosphere would probably support a much longer column.

So if you were on such a Planet, your mercury column would be #20.0*atmxx760" mm Hg"#.
