What height corresponds to an atmospheric pressure of 850 hPa?

An atmospheric pressure of 850 hPa corresponds to a height of approximately 5,000 feet. Understanding this relationship is crucial for pilots since atmospheric pressure decreases with altitude. The standard atmospheric pressure at sea level is about 1013 hPa (or 29.92 inHg), and as you ascend, the pressure decreases, typically losing about 12 hPa for every 1,000 feet climbed in the lower atmosphere.

At 5,000 feet, the pressure reaches around 850 hPa, which signifies that the altitude is just within the tropospheric region where most weather phenomena occur. Knowing this allows pilots to make more informed decisions regarding flight levels, altimeter settings, and weather assessments. This is why 5,000 feet is the correct answer in the context of atmospheric pressure measurements.
