What is the average air pressure recorded at the sea surface?

The correct answer is '1013.25 mb'

Key Points

• Average Air Pressure at Sea Level:
  • The average air pressure at sea level is internationally recognized as approximately 1013.25 millibars (mb), which is equivalent to 1013.25 hPa (hectopascals).
  • This value represents the standard atmospheric pressure and is used as a reference point for meteorological measurements.
  • Air pressure is the force exerted by the weight of the atmosphere above a given point, and it decreases with altitude.
  • 1013.25 mb is considered the "standard atmosphere" in scientific studies, particularly in aviation and weather forecasting.
