Convert PSI to kPa Instantly
Use this PSI to kPa converter to change pressure from pounds per square inch (psi) into kilopascals (kPa) instantly. Enter any whole or decimal PSI value to see kPa, bar, MPa and pascals, or switch to the reverse converter when your starting pressure is already in kilopascals.
Convert PSI to kPa, reverse kPa to PSI, compare PSI with bar and MPa, or convert one pressure value across PSI, kPa, bar, MPa and pascals.
Enter pressure in pounds per square inch to calculate kilopascals and related pressure units.
Decimals are supported, such as 32.5 psi or 72.25 psi.
Reverse the conversion by dividing kilopascals by 6.894757293.
Enter PSI to compare the same pressure in bar, megapascals and kilopascals.
Enter one pressure value and convert it among PSI, kPa, bar, MPa and pascals.
PSI means pounds per square inch, while kPa means kilopascals. Both measure pressure, but they belong to different measurement systems. To convert PSI to kPa, multiply by approximately 6.894757293.
For example, 10 psi is approximately 68.9476 kPa, 50 psi is approximately 344.7379 kPa, and 100 psi is approximately 689.4757 kPa.
Example: 50 psi × 6.894757293 ≈ 344.7379 kPa.
Example: 700 kPa ÷ 6.894757293 ≈ 101.5264 psi.
Pressure values appear in many forms. PSI is common in tires, compressors, hydraulics and U.S. equipment specifications, while kPa is widely used in metric engineering, automotive and scientific contexts.

PSI expresses force in pounds-force over an area of one square inch. The kilopascal is a metric pressure unit based on the pascal, where one pascal equals one newton per square meter. Because the underlying force and area units differ, the numerical values differ even though the physical pressure is the same.
The same pressure can be expressed in PSI, kPa, bar or MPa using fixed conversion relationships.
A PSI to kPa conversion is useful whenever a pressure value from an imperial or U.S.-style specification needs to be compared with a metric specification. Common examples include vehicle tire pressure, air compressors, pneumatic tools, hydraulic systems, pressure gauges, industrial equipment and engineering documentation.
For example, a tire pressure of 35 psi is approximately 241.3 kPa, while 100 psi is approximately 689.5 kPa.
PSI stands for pounds per square inch. kPa stands for kilopascals. Both measure pressure, but they use different base units. PSI is common in U.S. customary contexts, while kPa is part of the SI-derived metric pressure system.
One kilopascal equals exactly 1,000 pascals, while one megapascal equals exactly 1,000 kilopascals.
Tire-pressure labels may show PSI, kPa, bar or more than one of these units. For example, 32 psi is about 220.6 kPa, 35 psi is about 241.3 kPa and 40 psi is about 275.8 kPa.
Always follow the vehicle or tire manufacturer's specified pressure rather than choosing a value based only on a conversion chart.
Air compressors and pneumatic equipment may list operating pressure in PSI, kPa or bar. Converting the units allows you to compare a compressor's output with a tool's required pressure. For example, 90 psi is approximately 620.5 kPa or 6.205 bar.
Hydraulic systems often operate at much higher pressures than tires or pneumatic tools. A hydraulic specification may use PSI, bar or MPa. Since 1,000 kPa equals 1 MPa, large kPa values can often be expressed more conveniently in megapascals.
For example, 3,000 psi is approximately 20,684.27 kPa or 20.684 MPa.
Pressure units are related through fixed conversion factors. One bar equals exactly 100 kPa, one MPa equals exactly 1,000 kPa, and one kPa equals exactly 1,000 pascals.
PSI to kPa requires multiplying by about 6.894757.
1 MPa equals 1,000 kPa.
Unit conversion does not change the pressure reference.
Keep enough decimal precision until the final result.
Continue converting pressure with kPa to PSI, Bar to PSI, Bar to kPa, kPa to MPa, MPa to kPa and MPa to PSI. These related tools help when equipment and engineering documents use different pressure units.
For a quick estimate, multiply PSI by about 6.895. For higher precision, use 6.894757293. Useful landmarks include 10 psi ≈ 68.95 kPa, 30 psi ≈ 206.84 kPa, 50 psi ≈ 344.74 kPa and 100 psi ≈ 689.48 kPa.
