FAQ
What is atmospheric pressure?
What is atmospheric pressure?
Atmospheric pressure is the force exerted on the Earth's surface by the weight of the air above it. Every square centimeter of the Earth's surface experiences 1.033 kg of pressure from the air.
What's the standard atmospheric pressure?
What's the standard atmospheric pressure?
The standard atmospheric pressure for humans is 760 mm Hg. This is considered the most comfortable level, but the standard pressure varies with altitude: the higher the altitude, the lower the pressure.
How is atmospheric pressure measured?
How is atmospheric pressure measured?
Atmospheric pressure is measured using a special instrument called a barometer, which can be mercury, liquid, mechanical, or electronic. Millimeters of mercury (mmHg) is the standard unit of measurement for atmospheric pressure, but it is also commonly measured in hectopascals (hPa).
How does atmospheric pressure affect the weather?
How does atmospheric pressure affect the weather?
Atmospheric pressure varies with the formation and movement of large air masses that directly influence the weather. Low-pressure air vortices, known as cyclones, can have a central low-pressure area and a radius extending for thousands of kilometers.
