What is a Kilopascal?
Definition
A kilopascal (kPa) is a unit of pressure equal to 1,000 pascals. It measures force per unit area and is commonly used in engineering, meteorology, and automotive applications.
The kilopascal converter helps you easily change kPa values to other pressure units like PSI, bar, and atmosphere.
Common Uses
- • Tire pressure measurement (typically 200-250 kPa)
- • Weather reports and atmospheric pressure
- • HVAC system pressure readings
- • Medical equipment calibration
- • Industrial machinery specifications

Kilopascal Conversion Formulas
kPa to PSI:
PSI = kPa ÷ 6.89476
Example: 100 kPa = 100 ÷ 6.89476 = 14.5 PSI
kPa to Bar:
Bar = kPa ÷ 100
Example: 200 kPa = 200 ÷ 100 = 2 bar
kPa to atm:
atm = kPa ÷ 101.325
Example: 101.325 kPa = 101.325 ÷ 101.325 = 1 atm
kPa to mmHg:
mmHg = kPa ÷ 0.133322
Example: 13.3322 kPa = 13.3322 ÷ 0.133322 = 100 mmHg
