Question

Atmospheric pressure express in mm of hg rather than pascal ? Give reason ​

Answer 1

Answer:

1 atm = 101,325 Pascals = 760 mm Hg = 760 torr = 14.7 psi.

The standard atmosphere (symbol: atm) is a unit of pressure defined as 101,325 Pa (1,013.25 hPa; 1,013.25 mbar), which is equivalent to 760 mm Hg, 29.9212 inches Hg, or 14.696 psi.
