Definition
Atmospheres is a unit of pressure commonly used to measure atmospheric pressure. It represents the average pressure exerted by Earth's atmosphere at sea level.
Pascals are another unit of pressure used in scientific measurements. One atmosphere is equal to approximately 101,325 pascals.
Barometers: Barometers are instruments used to measure atmospheric pressure. They can be analog or digital and help us understand changes in weather patterns.
Altitude: Altitude refers to the height above sea level. As altitude increases, atmospheric pressure decreases because there is less air pressing down from above.
