Question: 1 / 400

What is standard sea level pressure measured in millibars?

1013.2 millibars

Standard sea level pressure is defined as 1013.2 millibars. This value is crucial in aviation and meteorology as it represents the average atmospheric pressure at sea level. Understanding this baseline allows pilots, dispatchers, and meteorologists to make accurate calculations related to flight performance, weather forecasting, and altimetry.

The other values presented relate to different measurements or contexts. For example, 29.92 inches of mercury is an equivalent measurement of atmospheric pressure, but it is not expressed in millibars. Similarly, 760 millimeters of mercury and 14.7 pounds per square inch are also representations of atmospheric pressure, but they do not define the standard sea level pressure in milibars. Hence, the universally accepted standard is 1013.2 millibars, making it vital for accurate analysis and operations in aviation.
