Barometric pressure is measured either in standard atmospheres (atm), Pascals (Pa), inches of mercury (inHg), or bars (bar). At sea level, the normal range for barometric pressure is:Between 101,325 Pa and 100,000 Pa. What level of barometric pressure causes headaches? Specifically, we fo...

Prior to about 1914 most measurements of pressure were made in inches of mercury (inHg), but all information in this paper is presented in contemporary units - with pressures reduced to mean sea level unless otherwise stated - and modern synoptic notation as far as possible. A complementary ...
1 hPa = 0.02953337 inHg (inches of mercury) 1 hpa = 0.00098692 atm (standard atmospheres) Temperature Effects Because temperature affects the density of a gas, and density affects the mass of a gas, and mass affects the pressure (whew), atmospheric pressure will change dramatically with temperat...

Pressureis returned in the SI units ofPascals. 100 Pascals = 1 hPa = 1 millibar. Often times barometric pressure is reported in millibar or inches-mercury. For future reference 1 pascal =0.000295333727 inches of mercury, or 1 inch Hg = 3386.39 Pascal. So if you take the pascal value of ...
