PSI to KPA Converter: Convert psi to kilopascals Instantly
Use this tool to convert pounds per square inch (psi) to kilopascals (kPa) quickly and accurately. Perfect for engineering, automotive, and scientific applications.
Understanding the Conversion from PSI to Kilopascals
Pressure is an essential parameter across various industries and scientific disciplines. The pounds per square inch (psi) and kilopascal (kPa) are two commonly used units of pressure. This converter simplifies the process of converting psi to kPa, offering reliable and fast results for anyone needing to switch between the imperial and metric systems.
What Is a Pound per Square Inch (psi)?
PSI stands for "pounds per square inch." It is a unit of pressure used primarily in the United States and other countries that follow the imperial system. One psi represents the pressure resulting from a force of one pound-force applied to an area of one square inch. PSI is used extensively in tire pressure measurements, hydraulics, and industrial machinery.
What Is a Kilopascal (kPa)?
The kilopascal is a metric unit of pressure where 1 kPa equals 1,000 pascals. The pascal (Pa) is the SI derived unit for pressure and is defined as one newton per square meter. Kilopascals are widely used in weather forecasting, physics, fluid mechanics, and engineering disciplines globally.
Conversion Formula
kPa = psi × 6.89476
Example: 10 psi × 6.89476 = 68.95 kPaPSI to KPA Conversion Table

Why Convert PSI to KPA?
Understanding and converting between these units is important in a variety of settings:
- Automotive: Tire pressure gauges and manufacturer specs in North America often use psi, while international manuals use kPa.
- Engineering: Global projects often require conversions between metric and imperial units.
- Industrial Applications: Compressors, pressure vessels, and pipelines often have readings in both psi and kPa.
- Academic and Scientific Research: Accurate unit conversions ensure consistent scientific calculations and data exchange.

FAQ: PSI to KPA
How many kPa are in 1 psi?
1 psi is equal to 6.89476 kPa.
How do I convert psi to kPa manually?
Multiply the psi value by 6.89476 to get the pressure in kilopascals.
Why are psi and kPa both used?
PSI is commonly used in the United States due to the imperial system, while kPa is used globally as part of the SI metric system. Instruments often display both for convenience.
Is this conversion accurate for all types of pressure?
Yes, this conversion applies to gas, liquid, and even atmospheric pressure as long as the units remain consistent.
Global Usage
- PSI: Widely used in the U.S. for tires, pumps, and industrial settings.
- KPA: The international standard for pressure measurements in scientific and engineering contexts.
- Devices are increasingly built with dual scales for ease of use across regions.
