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.
