Absolute Pressure is measured relative to a full vacuum (in the empty, air-free space), and uses absolute zero as its reference pressure. Pressure that is measured against Atmospheric Pressure (also known as Barometric Pressure) is called Gauge Pressure.
Average Barometric Pressure (1 ATM) at sea level is ~14.7 Psi (100 Kpa) or 1 Bar.
According to two picture,we can find the Formula for the Absolute Pressure:
Absolute Pressure = Atmospheric Pressure + Gauge Pressure

Atmospheric (Barometric) Pressure Sensor
The correct reading for the Atmospheric Pressure Sensor is between 50 kPa (7.3 psi) and 100 kPa (15 psi).
Altitude Derate
The engine may be derated due to high elevation. Use Cat ET to check for an active Engine Derate on the Status Flags screen.
Note: There are no event codes that are associated with the Altitude Derate.
