ssure Calibration Discussion
To compare pressure conditions from one location to another,
meteorologists correct pressure to sea-level conditions. Because the air
pressure decreases as you rise in altitude, the sea-level corrected
pressure (the pressure your location would be at if located at sea-level)
is generally higher than your measured pressure.
s, your absolute pressure may read 28.62 inHg (969 mb) at an
ssure is 30.00 inHg
he standard sea-level pressure is 29.92 inHg (1013 mb). This is the

d relative pressure measurements less than 29.92 inHg are
onsidered low pressure.
