What is the air pressure in millibars at the top of mt Everest?

The air pressure at the summit of Mount Everest, which stands at 8,848 meters (29,029 feet) above sea level, is approximately 300 millibars. This is significantly lower than the standard atmospheric pressure at sea level, which is about 1,013 millibars. The reduced air pressure at such high altitudes contributes to the challenges faced by climbers, including decreased oxygen availability.
