following units:
- hPa: Absolute pressure given in the unit of hPa.
- barg: Gauge pressure given in the unit of bar. Indicates the pressure difference between normal atmospheric pressure and the actual process pressure.
- bara: Absolute process pressure given in the unit of bar.
- psia: Absolute pressure given in the unit of psi.
