About Pressure Units

Pressure is the force applied perpendicular to the surface of an object per unit area. The SI unit for pressure is the pascal (Pa), where 1 kilopascal (kPa) equals 1000 pascals.

Common Pressure Values
  • Standard Atmospheric Pressure: 14.6959 PSI = 101.325 kPa
  • Recommended Car Tire Pressure: ~29-35 PSI = ~200-240 kPa
  • Bicycle Tire Pressure: ~58-116 PSI = ~400-800 kPa
About the Units

Pounds per Square Inch (PSI): PSI is a unit of pressure in the imperial and US customary systems. It represents the pressure resulting from a force of one pound-force applied to an area of one square inch. It's widely used in the United States for tyre pressure, gas pressure, and other everyday applications.

Kilopascal (kPa): The kilopascal is part of the International System of Units (SI) and is defined as 1,000 newtons per square meter (N/m²). It's commonly used in scientific, engineering, and meteorological applications worldwide.

Understanding the PSI to kPa Converter

The PSI to kPa converter is a handy tool designed for quick and easy pressure conversion. PSI stands for pounds per square inch, while kPa stands for kilopascals.
