What is the difference between absolute and relative pressure?

Absolute pressure is the measured atmospheric pressure. Absolute pressure is not corrected to sea-level conditions. To compare pressure conditions from one location to another, meteorologists correct pressure to sea-level conditions (referred to as relative pressure, or pressure relative to sea-level). Because the air pressure decreases as…
