About the Pascal (Pa)
The Pascal is the SI unit of pressure, defined as one newton of force per square meter — small enough that everyday pressures run in the thousands or millions of pascals.
About the Standard Atmosphere (atm)
The Standard Atmosphere is defined as exactly 101,325 pascals, representing average air pressure at sea level — used as a reference point across chemistry and engineering.
