No. Hg stands for 'inches of mercury'
1023 millibars is 30.213 inches of mercury.
Mercury
760 mm Hg is 1 atmosphere, so approx 1 bar. It is 1.013 bar, which is 1013 milibars.
The average air pressure at the summit of Brasstown Bald in Georgia is around 25.5 inches of mercury (Hg), or approximately 864 millibars. However, it can fluctuate due to weather conditions.
It is low, but the exact pressure varies, generally the lower the pressure, the stronger the hurricane. Most have pressures less than 995 millibars. On rare occasions the pressure in the very strongest of hurricanes can drop below 900 millibars.
The conversion factor for converting from Hg to millibars (hPa) is: 33.9
1023 millibars is 30.213 inches of mercury.
27.23 inches of mercury is 922.1 millibars.
Hg = Mercury
The actual conversion is: 29.92 in. Hg = 1013.25 millibars . . . both numbers represent standard sea-level pressure.
Hg stands for Mercury metal..only liquid state meta
33.8637526 1 Bar is an arbitrary "standard atmospheric pressure" which is roughly 29 and a half inches of mercury. If you multiply the inches-of-mercury value by 33.8637526 you get the pressure in millibars
MB in weather stands for Millibars, and is a measure of pressure in the atmosphere.
Mercury
760 mm Hg is 1 atmosphere, so approx 1 bar. It is 1.013 bar, which is 1013 milibars.
The standard atmospheric pressure is 14.7 psi which is equal to 1014 millibars and 760 mm Hg. Therefore 606 mm Hg = 606/760 of an atmosphere = 0.797 atm. Therefore in millibars it is 0.797 x 1014 = 808.5 mb. Now 1 mb = 100 Pa = 0.1 kPa, so 808.5 mb = 80.85 kPa.
At 13,000 feet above sea level, the average barometric pressure is around 559 millibars.
