About the units
- Psi
- One pound-force per square inch, about 6894.757 pascals from the exact definitions of the pound, inch and standard gravity.
- Kilopascal
- Exactly 1000 pascals, widely used for tyre pressure and engineering systems.
Limits and caveats
- Results are rounded for display and computed with the browser's floating point precision (about 15 significant digits).
- Both unit factors are exact by their official definitions.
Questions about this tool
How many kilopascals are in one psi?
1 psi = 6.89476 kPa exactly.
How do I convert psi to kilopascals?
Use kPa = psi × 6.894757293. For example, 25 psi = 172.369 kPa.
How many psi are in one kilopascal?
1 kPa = 0.145038 psi.
What is the difference between gauge and absolute pressure?
Gauge pressure is measured from the surrounding air pressure, while absolute pressure starts from a perfect vacuum. These converters change the unit only, so a gauge reading stays a gauge reading.
Are torr and mmHg the same?
Almost. One torr is 101325/760 Pa, about 133.322368 Pa, and one conventional mmHg is 133.322387 Pa, a difference of less than one part per million. For everyday use you can treat them as equal.
