About pascals
Pascal (Pa) — The pascal is the SI derived unit of pressure, equal to one newton per square meter.
Common uses: Pascals are used in physics, engineering, weather, fluid mechanics, material testing, and SI pressure specifications.
About standard atmospheres
Standard atmosphere (atm) — One standard atmosphere is exactly 101,325 pascals. It represents a conventional sea-level reference pressure, not a local weather reading.
Common uses: Standard atmospheres are used in physics, chemistry, engineering, gas laws, pressure references, and educational examples.
