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 tire pressure, gas pressure, and other everyday applications.
