About These Units
- Pascals (Pa)
- The SI derived unit of pressure, one newton per square meter, named after Blaise Pascal. A single pascal is tiny, so the bare unit mostly appears in acoustics, physics, and building airtightness tests.
- Atmospheres (atm)
- The standard atmosphere, defined as exactly 101,325 Pa to represent typical sea-level air pressure. Chemists use it for gas laws and standard conditions, and divers use it to describe the pressure at depth.
