What is the Atmospheric Pressure at Sea Level
The atmospheric pressure at sea level is the force per unit area exerted by the atmosphere on Earth’s surface. It is also known as barometric pressure and varies depending on the weather and altitude. The standard atmospheric pressure at sea level is 1013.25 hPa or 1 atmosphere (atm), but it can range from a low of 986 hPa during a hurricane to a high of 1060 hPa during a winter storm.
The average person experiences an atmospheric pressure of around 14.7 psi (pounds per square inch).
The atmospheric pressure at sea level is 14.7 pounds per square inch. This means that for every square inch of surface area on Earth, 14.7 pounds of air are pressing down on it. The atmosphere comprises different gases, including nitrogen, oxygen, and carbon dioxide.
What is the Atmospheric Pressure of Sea Level?
Climatic strain is the power per unit region applied by the environment on a surface in touch with it. At sea level, this force is due to the weight of air above the surface and is equal to 101325 pascals (Pa), or about 14.7 pounds per square inch (psi). The SI unit for atmospheric pressure is the pascal (Pa), defined as one newton per square meter (N/m2).
What is the Atmospheric Pressure at Sea Level in Pascals?
The atmospheric pressure at sea level in Pascals is 101325 Pa. This is also equal to 760 mmHg or 29.92 inches of mercury. The air pressure decreases with altitude, so on top of mountains, it can be much lower than this.
What is the Atmospheric Pressure at Sea Level in Pascal
The atmospheric pressure at sea level is 101325 Pascals. This is sometimes called “standard” or “normal” atmospheric pressure. It is also equal to 760 mmHg (millimeters) or 29.92 inches of mercury.
Atmospheric pressure decreases with altitude. For example, the atmospheric pressure at 5,000 meters (16,404 feet) above sea level is only about half of what it is at sea level. So, if you are going to be mountaineering or high-altitude activities, it is important to consider this and acclimatize accordingly.
Conclusion
Atmospheric pressure is the power per unit region applied against a surface by the heaviness of air over that surface in the atmosphere. Atmospheric pressure at sea level is 1013.25 hPa or 1 atmosphere (atm).
