1013.25 mbar abs
- Meaning: This value represents the standard atmospheric pressure at sea level. It is a reference point for measuring other pressures, such as gauge pressure or differential pressure. The “abs” indicates that the pressure is measured relative to a perfect vacuum (absolute pressure).
 - Specificity: This value is specific because it defines a standard condition for pressure measurements. It allows for consistent comparisons and calculations across different locations and altitudes.
 - Applications:
- Pressure calibration: Used to calibrate pressure sensors and transducers.
 - Altitude measurements: Related to atmospheric pressure, which decreases with altitude.
 - Meteorology: Used in weather forecasting and analysis.
 - Engineering calculations: Serves as a reference point for various engineering calculations involving pressure.
 - Vacuum systems: Can be used to determine the degree of vacuum in a system.
