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

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.

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.

Understanding Pressure Units: kPa and PSI

Pressure is all around us and affects many aspects of our daily lives. Two common units used to measure pressure are kilopascals (kPa) and pounds per square inch (PSI). Understanding these units helps in various fields like engineering, automotive, and even cooking. The kilopascal is widely used in scientific contexts, while PSI is more common in the United States, particularly for measuring tire pressure and Other everyday applications.
