About kPa and PSI Conversion

Pressure measurement is essential in various fields including engineering, automotive, aviation, and industrial applications. This free online tool provides instant conversion between kilopascals (kPa) and pounds per square inch (PSI).

What is kPa?

Kilopascal (kPa) is a metric unit of pressure. 1 kPa is equal to 1,000 pascals. It is commonly used in countries that use the metric system to measure pressures such as tire inflation, scuba tank pressure, and industrial processes.

What is PSI?

Pounds per square inch (PSI) is an imperial unit of pressure. It measures the force in pounds applied on one square inch of area. PSI is commonly used in the United States for applications such as tire pressure, hydraulic systems, and scuba diving.

Conversion Formula

1 kPa = 0.14503773779 PSI

1 PSI = 6.8947572932 kPa

Common Applications

  • Automotive tire pressure measurements
  • Scuba diving tank pressure
  • Industrial hydraulic systems
  • HVAC system pressures
  • Scientific research and experiments

Frequently Asked Questions

Why do I need to convert kPa to PSI?

Different countries and industries use different pressure units. Converting between kPa and PSI is essential when working with international equipment specifications, vehicle manuals, or scientific data that use different measurement systems.

How accurate is this kPa to PSI converter?

Our converter uses precise conversion factors with calculations accurate to 6 decimal places. For most practical applications like automotive tire pressure or industrial use, this level of precision is more than sufficient.

What is the difference between kPa and PSI?

kPa (kilopascal) is a metric unit where 1 kPa = 1,000 pascals, while PSI (pounds per square inch) is an imperial unit that measures force per area. 1 PSI is approximately equal to 6.895 kPa. kPa is widely used globally, while PSI is more common in the United States.
