Pascals to Kilopascals Conversion Table
Common values, ready to copy:
| pascals | kilopascals |
|---|---|
| 1 Pa | 0.001 kPa |
| 2 Pa | 0.002 kPa |
| 5 Pa | 0.005 kPa |
| 10 Pa | 0.01 kPa |

Formula
kilopascals = pascals × 0.001
Pressure is force per area. 1 atm = 101.325 kPa = 14.696 psi = 760 mmHg. Bar is a metric working unit close to atmospheric pressure (1 bar = 100 kPa).
About Pascals and Kilopascals
Pascals (Pa): The SI unit of pressure, defined as one newton per square meter; named for Blaise Pascal, who established fundamental principles of fluid pressure in the 17th century. Common uses: Scientific work, weather (atmospheric pressure in hectopascals or kilopascals), and engineering specifications.
Kilopascals (kPa): A thousand pascals; the practical SI pressure unit for atmospheric and engineering work. Common uses: Weather reports (atmospheric pressure in kPa, where standard sea-level pressure is about 101 kPa), tire pressure in many countries, and structural engineering.
How the conversion works
Pressure is force per area. 1 atm = 101.325 kPa = 14.696 psi = 760 mmHg. Bar is a metric working unit close to atmospheric pressure (1 bar = 100 kPa).
The exact relationship is kilopascals = pascals × 0.001, which the calculator at the top of this page applies in both directions. Type into either field and the other updates immediately.
When this conversion matters
Converting between pascals and kilopascals comes up wherever pressure measurements move between systems — from one country's conventions to another's, from a scientific reference to a practical specification, or from one industry's working unit to another's. The calculator and reference table above cover the everyday range; for unusual values you can type any number into either field.
