KPA to PSI Converter: Convert kPa to psi Quickly
Use this tool to convert kilopascals (kPa) to pounds per square inch (psi) quickly and accurately—perfect for industrial, engineering, and scientific use.
Understanding the Conversion from Kilopascals to Pounds per Square Inch
Pressure measurements are crucial in various fields like engineering, meteorology, and scientific research. Two widely used units for measuring pressure are kilopascals (kPa) and pounds per square inch (psi). This tool helps you convert between these two units easily, allowing for smoother transitions between different measurement systems.
What Is a Kilopascal (kPa)?
The kilopascal (kPa) is a metric unit of pressure, where one kilopascal is equal to 1,000 pascals. The pascal (Pa) itself is the SI (International System of Units) derived unit for pressure, defined as one newton per square meter. Kilopascals are widely used in scientific, engineering, and meteorological applications around the world.
What Is a Pound per Square Inch (psi)?
The pound per square inch (psi) is a unit of pressure commonly used in the imperial system, particularly in the United States. It represents the force of one pound applied to an area of one square inch. PSI is used in a wide range of applications, including tire pressure, air compressors, and various industrial settings.
Conversion Formula
PSI = kPa ÷ 6.89476
Example: 100 kPa ÷ 6.89476 = 14.50 psiKPA to PSI Conversion Table

Why Convert Kilopascals to Pounds per Square Inch?
There are many reasons you may need to convert kilopascals to psi:
- Industrial Applications: Many machines, air systems, and hydraulic systems in the U.S. use psi as the standard unit for pressure.
- Engineering and Science: Engineers and scientists may need to convert pressure measurements between metric and imperial systems for accuracy and standardization.
- Automotive: Tire pressures are often specified in psi in the U.S., while international standards may use kPa.
- Meteorology: Atmospheric pressure is typically measured in kPa, but some weather stations in the U.S. report pressure in psi.

FAQ: KPA to PSI
How many psi are in 100 kPa?
100 kPa equals approximately 14.50 psi.
How do I convert kPa to psi quickly?
To convert kPa to psi, divide the number of kilopascals by 6.89476.
Why is kPa used globally while psi is more common in the US?
kPa is a metric unit, part of the International System of Units, used worldwide. PSI is a non-metric unit used primarily in the United States due to historical reasons and the persistence of the imperial system.
Can I use this converter for liquid pressures as well?
Yes, this converter works for both gas and liquid pressure conversions, as the pressure calculation remains the same for both phases.
International Perspective
- KPa: Used globally in scientific, industrial, and engineering applications.
- PSI: Predominantly used in the United States and some specific industrial settings.
- Many devices and instruments include both kPa and psi to cater to different regions.
Conclusion
Whether you're working in engineering, automotive, or scientific fields, understanding how to convert kilopascals to psi is essential for global compatibility. This tool helps you make accurate pressure conversions effortlessly, bridging the gap between metric and imperial measurement systems.
