What is the pressure at sea level in your opinion Not my opinion, it's a scientific fact: Mean sea level pressure Average sea-level pressure is 1013.25 mbar (101.325 kPa; 29.921 inHg; 760.00 mmHg). In aviation weather reports ( METAR), QNH is transmitted around the world in millibars or hectopascals (1 hectopascal = 1 millibar), except in the United States, Canada, and Colombia where it is reported in inches (to two decimal places) of mercury. The United States and Canada also report sea level pressure SLP, which is adjusted to sea level by a different method, in the remarks section, not in the internationally transmitted part of the code, in hectopascals or millibars. [2] However, in Canada's public weather reports, sea level pressure is instead reported in kilopascals. [3] en.wikipedia.org Of course place and time is important. Before I take off to fly my plane (glider) I reset my altimeter to actual field elevation so that it is referenced to MSL. And before landing I get station reports to reset it for accuracy depending on where I land. SOP for pilots.
