Pascal to Kilopascal (Pa to kPa)
Result
0.001 Kilopascal
Formula
kPa = Pa × 0.001
1 Pa = 0.001 kPa, and 1 kPa = 1,000 Pa.
The pascal is one newton per square metre. The bar is exactly 100,000 Pa, the standard atmosphere exactly 101,325 Pa, the torr exactly 1/760 atm, and psi is one pound-force per square inch (6,894.757 Pa).
Worked examples
- 1 Pa × 0.001 = 0.001 kPa
- 10 Pa × 0.001 = 0.01 kPa
- 100 Pa × 0.001 = 0.1 kPa
Common mistakes
- Tyre and compressor gauges read gauge pressure — pressure above the surrounding air. Absolute pressure is about 1 atm (14.7 psi, 1.013 bar) higher.
- Weather maps use hectopascals (1 hPa = 100 Pa = 1 millibar); standard sea-level pressure is 1,013.25 hPa.
- Torr and mmHg differ by less than one part per million and are interchangeable for practical purposes.
