6. Indicates whether the air pressure is shown in hPa (hectoPascal), in inHg (inch mercury pressure) or

mmHg (millimeter mercury pressure) (see also * add 6)

* add 5: An absolute air pressure indicates the air pressure that is present regardless of the altitude at which

you measure the air pressure. A relative air pressure is the air pressure that is compensated for the altitude

at which you measure the air pressure. For a correct weather forecast you need the relative air pressure.
