The average barometric pressure change in Tucson, Arizona during monsoon season is from 14 to 25 degrees Celsius. It is the season of heavy rains and strong winds.
In general, barometric pressure, or atmospheric pressure, drops as you go up in elevation. For example, at 18,000 ft. above sea level, the average barometric pressure is about half the average pressure at sea level (see the related links for charts) However, barometric pressure also varies widely with the weather (weather charts almost always show the movement of low pressure and high pressure zones), so true barometric pressure cannot simply be calculated, but must be measured. In the United States, the National Oceanic and Atmospheric Administration provides hourly barometric readings for many locations across the country (see related National Weather Service measurement link)
The average pressure on the surface of Venus is about 90 to 100 times greater than the pressure on Earth, according to most of the websites I visited doing research. That's about 90 bars.
The atmospheric pressure at Venus's surface is 92 times that of the Earth's surface. So that's 92.92 x 105 Pa
According to measurements of Viking spacecrafts the average pressure is around 0.7% of the normal pressure on the Earth, but they are large seasonal variations due to freezing of carbon dioxide from the atmosphere during the winter.

Slightly above but not by much. 760 mm Hg = 1 ATM . 1 ATM is considered average.
pressure is measured in "bar" 1bar is equal to 1000millibar. this is the atmospheres base pressure. 1020millibar is high atmospheric presure. 980 mb is low air pressure. 1.02 or 0.98 bar
Atmospheric pressure varies with altitude and air density. Average sea-level pressure is 101.325 kPa (1013.25 mbar) or 29.921 inches of mercury (inHg) or 760 millimeters of mercury (mmHg).
I don't think there is a good answer to this question. Until just recently, almost nothing was known of its atmosphere. Its atmosphere is constantly being generated from its mass, but due to the heat and solar wind, it is almost immediately lost. I presume that means the pressure varies greatly from time to time, as well as from the dayside to the nightside. I hope that helps. I have something to say too! That person ^ had a good point but i have the real answer... The daily Barometric pressure on mercury is Max Barometric Pressure: 291.0 (inHg-27)*100 Average Barometric Pressure: 291.0 (inHg-27)*100 Current Barometric Pressure: 291.0 (inHg-27)*100 my source.. http://wb9tlh.ampr.us/weather/barometric_pressure/barometer.html
