How many PSI are in 1 kilopascal?
1 kPa ≈ 0.145038 psi.
How many PSI is 100 kPa?
100 kPa ≈ 14.503774 psi.
What do kPa and psi measure?
Both kilopascals (kPa) and pounds per square inch (psi) are units used to measure pressure.
What is the difference between kPa and psi?
The kilopascal is a metric/SI-derived pressure unit, while pounds per square inch is commonly used in the United States and other applications that use customary or imperial-style measurements.
Where are kPa and psi commonly used?
They are commonly used for measurements such as tire pressure, air pressure, hydraulic and pneumatic systems, compressors, and industrial equipment.
When You Might Need to Convert Kilopascals to PSI
Converting kilopascals to PSI is useful when working with pressure measurements that use different unit systems. You may need this conversion when:
- Checking vehicle or bicycle tire pressure
- Comparing air compressor specifications
- Working with hydraulic or pneumatic equipment
- Reading pressure ratings for tools, machinery, or industrial equipment
- Comparing international product specifications
- Working with HVAC, plumbing, or mechanical systems
- Interpreting pressure measurements provided in kPa when your equipment or reference materials use psi

About Kilopascals and PSI
A kilopascal (kPa) is a unit of pressure in the metric system and the International System of Units (SI). One kilopascal equals 1,000 pascals (Pa). Kilopascals are commonly used to measure tire pressure, air pressure, fluid pressure, and pressure in engineering, industrial, and mechanical applications.
Pounds per Square Inch (psi)
Pounds per square inch (psi) is a unit of pressure commonly used in the United States. It represents the amount of force in pounds-force applied over an area of one square inch. PSI is frequently used for tire pressure, compressed air, hydraulic systems, and equipment pressure ratings.
1 kPa ≈ 0.1450377377 psi.
For additional information about metric measurement and SI units, visit the U.S. National Institute of Standards and Technology (NIST).
Understanding the difference between these pressure measurement systems is especially useful when comparing equipment, products, or technical specifications from different countries. Kilopascals (kPa) are widely used in countries that follow the metric system, while pounds per square inch (psi) is commonly used in the United States. Whether you are checking tire pressure, comparing equipment specifications, working with compressed air, or interpreting mechanical pressure ratings, an accurate kilopascals to PSI conversion helps ensure that you are working with the correct pressure measurement.
For fast and accurate results, use our kilopascals to PSI converter whenever you need to compare pressure measurements between kilopascals (kPa) and pounds per square inch (psi).
