It isn't constant anywhere, no. 1013.25 mb is simply the average pressure, which is particularly important at sea level because that is how observations are standardized. But atmospheric pressure always varies no matter where you are, as a consequence of having weather.
it's the standard pressure at which all pilots set their altimeter, when communicating Fight Levels.
Atmospheric pressure is measured by a barometer and expressed in millibars. Normal atmospheric pressure at sea level is 1013 millibars.
The normal barometric pressure in Phoenix, Arizona is around 29.92 inches of mercury (inHg) or 1013 millibars (mb). This is considered standard atmospheric pressure at sea level.
The air pressure at sea level is typically around 1013 millibars or 29.92 inches of mercury.
The best atmospheric pressure for the human body is around 1013 millibars or 1 atmosphere. This pressure allows our lungs to easily expand and contract for breathing, and it supports the normal functioning of our circulatory system. Any significant increase or decrease in atmospheric pressure can lead to discomfort or health issues.
Average pressure at sea level is 1013.25 mbar
Normal atmospheric pressure is around 1013.25 millibars (MB) at sea level. However, this value can vary slightly depending on weather conditions and altitude.

Atmospheric pressure is measured by a barometer and expressed in millibars. Normal atmospheric pressure at sea level is 1013 millibars.
Simply put, atmospheric pressure is the force exerted on a measuring point by the weight of the air molecules on top of that point. Standard atmospheric pressure, measured at sea level at 59F or 15C, is used as a reference point and is equal to 29.92 inches of mercury or 1013 millibars of pressure.
The normal barometric pressure in Phoenix, Arizona is around 29.92 inches of mercury (inHg) or 1013 millibars (mb). This is considered standard atmospheric pressure at sea level.
The average atmospheric pressure at the equator is around 1013 millibars or 14.7 pounds per square inch. This pressure can vary slightly due to changes in weather patterns and altitude above sea level.
The air pressure in grasslands is typically around 1013 hPa (hectopascals), which is the average atmospheric pressure at sea level. However, air pressure can fluctuate due to weather conditions such as high or low-pressure systems moving through the area.
1013 mb
1013 millibar or 762 mm of Mercury
Pascal defined atmospheric pressure as an atmosphere over a meter being 1013 millibars at sea level and 20 deg C Newton stated it to be a Kg over a meter being 1.013 Kpa
The air pressure at sea level is typically around 1013 millibars or 29.92 inches of mercury.
