How do you calculate absolute pressure when barometer reading is given?
You do nothing. The reading from the barometer is absolute pressure.
Can humidity effect the reading of a barometer?
No , a Barometer measures air pressure.
What predictions about the weather can be made as the barometer reading falls?
if the barometer reading falls it means bad weather is coming
What is the use of barometer in detail?
barometer is an instrument used to measure the pressure in the atmosphere and it also gives as an accurate reading.

How can an aneroid barometer give reading in inches of mercury when it doesn't use any mercury?
Good question.Look at it like this if you had two barometers side by side, one a mercury barometer and the other a barometer that reacted to changes in air pressure using some bellows and a spring.Then, as the pressure changed you marked the second barometer positions and noted on the dial the inches reading from the mercury barometer, the second barometer measurement scale would mimic the real mercury barometer even though it did not actually use any mercury.
What is air pressure at Denver Colorado?
Air pressure is measured in different ways. Two common ones are PSI (pounds per square inch) or a barometer which measures in column inches of mercury. As we know the barometer goes up and down with weather so the air pressure goes up and down. The highest barometer reading ever recorded is about 32 inches or just over 15.6 PSI. The lowest barometer reading ever recorded was 25.69 in the middle of a hurricane so this is not typical but equates to about 12.5 PSI. These are all sea level readings. So we need an average, or normal. The standard is a barometer of 29.92 which equates to about 14.7 PSI, again being a sea level reading. With that standard the pressure at Denver is 12.1 PSI or a barometer of about 24.63. At this pressure water boils at about 202F instead of 212F.
What does low pressure reading in a barometer mean?
Generally it means it is going to rain.
