Detailed explanation-1: -The pressure altimeter is an aneroid barometer that measures the pressure of the atmosphere at the level where the altimeter is located and presents an altitude indication in feet. The altimeter uses static pressure as its source of operation.
Detailed explanation-2: -An aneroid barometer which has its scale calibrated in terms of height of ascent can be used as an altimeter. Since atmospheric pressure decreases with the increase in height above the sea level, therefore a barometer measuring the atmospheric pressure is used to determine the altitude.
Detailed explanation-3: -The measurement of altitude is called altimetry, which is related to the term bathymetry, the measurement of depth under water. The most common unit for altimeter calibration worldwide is hectopascals (hPa), except for North America (other than Canada ) and Japan where inches of mercury (inHg) are used.
