Kilopascal (kPa)
The kilopascal (kPa) equals 1000 pascals. It is the everyday SI unit for tyre pressure, gas supply pressure and atmospheric pressure.
Symbol: kPa
Quantity: pressure, stress and differential pressure (force per unit area)
SI relation: 1 kPa = 1000 Pa (exact)
Derivation: 1 kPa = 10³ Pa
Exact: yes, by definition
Typical uses
- Tyre pressure outside the United States (about 200–250 kPa for cars)
- Atmospheric pressure (101.325 kPa at sea level)
- Pump and compressor ratings
- Soil bearing capacity in geotechnical engineering
