29.92 inches of Mercury, which is the average atmospheric pressure on Earth at sea level, is about 14.7 pounds per square inch.
Altimeter 2992 means that the air pressure is 29.92 in. HG. 29.92 in. HG. With this information, you would calibrate your altimeter to 29.92.
150 mm Hg is the same as 2.90 PSI: 1 atmosphere == 760 mm Hg, so 150 mm Hg is the same as 0.197 atm. 1 atmosphere = 14.696 PSI so (0.197)(14.696) = 2.90 PSI
This value is 51,71493 mm col. Hg..
27,68089 inch of water = 1 psi 51,715 mm of mercury = 1 psi; 742 col. Hg = 14,347 psi 742 col. Hg = 0,515 inch of water
C. 21.13 psi
760 mm hg = 0 psi gauge pressure
ATM, psi, mm hg ATM is the scientific one. 1 ATM = 760 mm hg
