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.
Kilopascal (kPa)
- Definition
- A kilopascal (kPa) is 1,000 pascals, a convenient size for everyday pressures.
- History
- It is a metric multiple of the pascal.
- Current use
- Kilopascals express tyre pressure and atmospheric pressure in many countries.
