higher than your measured pressure.
Thus, your absolute pressure may read 28.62 inHg (969 mb) at an altitude of 1000 feet (305 m),
but the relative pressure is 30.00 inHg (1016 mb).
The standard sea-level pressure is 29.92 in Hg (1013.2hpa). This is the average sea-level pressure
around the world. Relative pressure measurements greater than 29.92 inHg (1013.2hpa) are
considered high pressure and relative pressure measurements less than 29.92 inHg are considered
low pressure.
To determine the relative pressure for your location, locate an official reporting station near you
(the internet is the best source for real time barometer conditions, such as Weather.com or
Wunderground.com), and set your weather station to match the official reporting station.
