About these units
Atmosphere (atm)
- Definition
- A standard atmosphere (atm) is defined as exactly 101,325 pascals, roughly average sea-level pressure.
- History
- It was standardised as a reference pressure for scientific work.
- Current use
- Atmospheres are used in chemistry, physics, and diving as a reference pressure.
Pascal (Pa)
- Definition
- The pascal (Pa) is the SI unit of pressure, equal to one newton of force per square meter.
- History
- Named after Blaise Pascal, it was adopted as the SI pressure unit in 1971.
- Current use
- Pascals and kilopascals are used in science, engineering, and weather reporting.
