Another question that makes me go...#"grrrr......."#

Explanation:

See this old answer.

#1*atm# will support a column of mercury that is #760*mm# high. A mercury column is thus a good tool to measure a pressure NEAR to one atmosphere, or LESS than one atmosphere. You do not use a mercury to measure a pressure that IS SUBSTANTIALLY OVER #1*atm#...this question should be retired as it is not realistic.
