What altitude is indicated by a pressure level of 250 hPa?

The altitude indicated by a pressure level of 250 hPa corresponds to roughly 34,000 ft. The calculation involves using the standard atmospheric model, where the pressure decreases as altitude increases. At sea level, the standard atmospheric pressure is approximately 1013 hPa, and as you go higher, the pressure decreases significantly.

At a pressure level of 250 hPa, which is found in the upper troposphere and often associated with jet stream activity, the altitude is higher than typical cruising altitudes for most general aviation and commercial aircraft. Therefore, while 5,000 ft and other lower altitudes are much more common for general flying, the correct altitude for 250 hPa pressure is indeed closer to 34,000 ft. This altitude is significant for understanding weather patterns and flight planning, particularly in relation to turbulence and wind patterns aloft.
