Understanding Kilopascals and Pounds per Square Inch

Kilopascal (kPa)

The kilopascal (kPa) is a unit of pressure within the International System of Units (SI), equivalent to one thousand pascals. It is commonly used worldwide in scientific and engineering contexts to measure pressure, stress, and modulus of elasticity. In several countries, including Canada, it is the standard unit for atmospheric pressure in weather reporting.

Pound per Square Inch (psi)

The pound per square inch (psi) is an imperial and US customary unit of pressure. It defines the pressure resulting from a one-pound force applied to an area of one square inch. This unit remains prevalent in the United States and other regions using imperial systems, especially in automotive, industrial, and engineering applications.

The kPa to psi Conversion Formula

The key to converting between these units is the conversion factor. To convert a pressure value from kilopascals to pounds per square inch, you multiply by approximately 0.1450377.

pressure (psi) = pressure (kPa) × 0.1450377

For example, converting 40 kPa involves a simple multiplication: 40 kPa × 0.1450377 ≈ 5.80 psi.

Conversely, to convert from psi to kPa, you divide the psi value by the same conversion factor, 0.1450377.

pressure (kPa) = pressure (psi) / 0.1450377

For instance, a pressure of 150 psi converts to kilopascals as follows: 150 psi / 0.1450377 ≈ 1034.21 kPa. Our free scientific calculator automates these calculations, ensuring speed and precision.

Frequently Asked Questions

How do I convert pressure from kPa to psi?
