By definition 1 ATM is the air pressure at sea level. The pressure at sea level also corresponds to the amount of air pressure that will support a column of Mercury 760 mm high at 0 degrees Celsius under standard gravity, or 14.7 pounds per square inch (1.01325 × 105 pascals). Consequently, 1 ATM = 760 mm Hg.

Fran760 mmHg is equal to 1 atmosphere because it is the average atmospheric pressure at sea level. This relationship was established by Torricelli's experiments with mercury in a barometer, which led to the definition of the standard atmosphere as the pressure needed to support a column of mercury 760 mm high.

What is 760 mm atmospheric pressure?
760 mm Hg is 1 atmosphere, so approx 1 bar. It is 1.013 bar, which is 1013 milibars.
How many atmospheres are equal to 790 mm Hg?
790 mm Hg is equal to approximately 1.04 atmospheres.
20 psi is how many mm of Hg?
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
What is the temperature equal to of 725 mm Hg?
All other factors being equal, the height of the column in a barometer is inversely related to the density of the material in that column. So we can write H = h (Rho/rho); where h = 745 mm Hg, H = ? mm in water, Rho = 13550 kg/m^3 Hg density and rho = 997 kg/m^3 water density. So we have H = 745*(13550/997) = 10125.12538 mm ~ 10.1 m when all other factors are equal. ANS.
Is 0 mm hg equal to 0 psia and is 760 mm hg equal to 0psig?
0 mmHg is equivalent to 0 psia because both represent a pressure of zero relative to absolute vacuum. However, 760 mmHg is equal to 14.7 psia, not 0 psig. 760 mmHg is equivalent to atmospheric pressure, which is the reference point for psig.
