One standard atmosphere (1 atm) equals exactly 101,325 pascals. This value was standardized based on the average atmospheric pressure at sea level.
The atmosphere is used in chemistry for gas law calculations, in diving to express underwater pressure, and in aerospace engineering. It provides an intuitive reference to sea-level air pressure.
Atmospheric pressure decreases roughly 12 Pa per meter of altitude gain near sea level. At 5,500 meters elevation, pressure drops to about 0.5 atm (50,663 Pa).
One standard atmosphere (atm) equals 101,325 Pa. A technical atmosphere (at) equals exactly 98,066.5 Pa (1 kgf/cm²). The standard atmosphere is more widely used in science.
