What is Absolute Pressure?

Absolute pressure is measured relative to a full vacuum. In contrast, the pressure that is measured against atmospheric pressure (also known as barometric pressure) is called gauge pressure. A full vacuum has an absolute pressure reading of 0 PSIA and average barometric pressure at sea level is ~14.7 PSIA.

How to measure Absolute Pressure?

Absolute Pressure is measured by pressure transducers for weather forecasting purposes are measuring the absolute pressure of the surrounding area. If the intended application uses gauge pressure transducers instead of absolute pressure transducers, readings would constantly be 0.

How to Calculate Absolute Pressure?

Absolute Pressure calculator uses Absolute Pressure=Atmospheric Pressure+Vacuum Pressure to calculate the Absolute Pressure, Absolute Pressure is labeled when any pressure is detected above the absolute zero of pressure. Absolute Pressure and is denoted by Pabs symbol.

How to calculate Absolute Pressure using this online calculator? To use this online calculator for Absolute Pressure, enter Atmospheric Pressure (Patm) and Vacuum Pressure (Pa) and hit the calculate button. Here is how the Absolute Pressure calculation can be explained with given input values -> 104525 = 101325+3200.

FAQ

What is Absolute Pressure?
Absolute Pressure is labeled when any pressure is detected above the absolute zero of pressure and is represented as Pabs=Patm+Pa or Absolute Pressure=Atmospheric Pressure+Vacuum Pressure. Atmospheric pressure, also known as barometric pressure, is the pressure within the atmosphere of Earth and Vacuum pressure is the difference between the atmospheric pressure and the absolute pressure.
How to calculate Absolute Pressure?
Absolute Pressure is labeled when any pressure is detected above the absolute zero of pressure is calculated using Absolute Pressure=Atmospheric Pressure+Vacuum Pressure. To calculate Absolute Pressure, you need Atmospheric Pressure (Patm) and Vacuum Pressure (Pa). With our tool, you need to enter the respective value for Atmospheric Pressure and Vacuum Pressure and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
