How to Convert Kilopascals to PSI
To convert kilopascals to psi, multiply the pressure by the following conversion ratio: 0.1450377 psi/kilopascal.
Since one kilopascal is equal to 0.1450377 psi, you can use this simple formula to convert:
The pressure in psi is equal to the pressure in kilopascals multiplied by 0.1450377.
For example, here's how to convert 220 kilopascals to psi using the formula above.
How Many PSI Are in a Kilopascal?
There are 0.1450377 psi in a kilopascal, which is why we use this value in the formula above.
Our kilopascal to pounds per square inch calculator automatically converts your pressure measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
Kilopascals and psi are both units used to measure pressure. Keep reading to learn more about each unit.
What Is a Kilopascal?
A kilopascal is a unit of pressure equal to 1,000 pascals (Pa), the base unit for pressure. Equal to 1,000 Pascals (1 kN/m²). [1]
The kilopascal is classified as a metric and SI-compatible unit of pressure. Kilopascals can be abbreviated as kPa; for example, 1 kilopascal can be written as 1 kPa.
In the metric system, "kilo" is the standard SI prefix for thousands, or 10³. This makes the kilopascal (kPa) a convenient decimal multiple of the pascal (Pa).
In practice, kilopascals (kPa) are widely used across large-scale industrial, bulk, and macro-level pressure specifications within SI metric workflows, engineering documentation, and technical data sheets.
What Is a Pounds per Square Inch?
A pounds per square inch is a unit of pressure equal to 6,894.7572932 pascals (Pa), the base unit for pressure. Imperial & US pressure unit equal to 1 pound-force per square inch (6.89476 kPa). [2]
The pounds per square inch is classified as a US customary and imperial unit of pressure. PSI can be abbreviated as psi; for example, 1 pounds per square inch can be written as 1 psi.
When working with psi (psi) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, psi (psi) are widely used across large-scale industrial, bulk, and macro-level pressure specifications within US customary and imperial workflows, engineering documentation, and technical data sheets.
When converting pressure between kilopascals (kPa) and psi (psi), keep full floating-point precision (1 kPa = 0.1450377 psi; 1 psi = 6.8947573 kPa) during intermediate calculations and round only the final pounds per square inch figure to match your instrument tolerance.
