What is the standard atmospheric pressure in millibars at sea level?

Explanation:
The standard atmospheric pressure at sea level is defined as 1013.25 millibars. This value is the baseline used in the International Standard Atmosphere for aviation and flight calculations, including calibrating altimeters. Millibars and hectopascals are the same pressure unit, just named differently, so 1013.25 mb equals 1013.25 hPa. It also corresponds to 29.92 inches of mercury. While other numbers like 1000, 990, or 1020 may be used as rough references, 1013.25 mb is the precise standard value.
