    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.
