Reference pressure of about 29.92 [[inHg (1013 hPa) is showing in the Kollsman window.]] An altimeter, or altitude meter, is an instrument used to measure the altitude of an object relative to a fixed level. The measurement of altitude is called altimetry, which is related to the term bathymetry, the measurement of depth under water.
An altimeter is an instrument that measures how high an object is above a fixed reference level, such as sea level or ground level. This measurement is important for aircraft and other applications where knowing altitude is critical for safe operation and navigation.
