How it is calculated
kPa = psf × 0.04788025898
Multiply the value in psf by 0.04788025898 to get kilopascals.
Example
To convert 25 psf to kilopascals: 25 × 0.04788025898 = 1.19701 kPa.

About the units
- Psf
- One pound-force per square foot, 1/144 of a psi, used for building and wind loads.
- 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 psf?
1 psf = 0.0478803 kPa exactly.
How do I convert psf to kilopascals?
Use kPa = psf × 0.04788025898. For example, 25 psf = 1.19701 kPa.
How many psf are in one kilopascal?
1 kPa = 20.8854 psf.
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.
