An altimeter is an aneroid barometer which makes use of the change in atmospheric pressure with the change in height above the sea level (altitude). How does the atmospheric pressure change with increase in height above the sea level?

An altimeter is an aneroid barometer which makes use of the change in atmospheric pressure with the change in height above the sea level (altitude). What is the approximate value of atmospheric pressure at sea level in S.I unit?

At sea level, atmospheric pressure is
