PSI (lb/in²)
14.50
Kilopascals (kPa)
99.97

Calculation Information

Input Value: 14.50 PSI

Formula Used: kPa = PSI × 6.89475729318

Step 1: Multiply PSI by 6.89475729318

14.50 × 6.89475729318 = 99.97 kPa

Result: 14.50 PSI = 99.97 kPa

Conversion Formulas

kPa = PSI × 6.89475729318
PSI = kPa × 0.14503773773

These formulas allow for precise conversion between pounds per square inch and kilopascal pressure units.

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 tire 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.

FAQs About PSI and kPa Conversion

What is PSI?

PSI (pounds per square inch) is a pressure unit used mostly in the United States. It describes the force of one pound-force applied to an area of one square inch.

What is kPa?

kPa (kilopascal) is a metric unit of pressure used worldwide. 1 kilopascal equals 1,000 pascals, and it's part of the SI (International System of Units).

Why are both units important?

PSI is commonly used in industries like automotive and HVAC, while kPa is standard in scientific, meteorological, and international settings. This calculator bridges the gap between both.

Is the conversion accurate?

Yes, this calculator uses highly accurate constants:

  • 1 PSI = 6.89475729318 kPa
  • 1 kPa = 0.14503773773 PSI
