Conversion of 80 psi equals approximately 551.6 kpa.
Since 1 psi equals about 6.89476 kilopascals (kpa), multiplying 80 by this factor gives the conversion result: 80 × 6.89476 = 551.5808, which rounds to 551.6 kpa.
Introduction to psi and kpa
Psi (pounds per square inch) measures pressure based on force in pounds applied over an area of one square inch. Kilopascal (kpa) is a metric pressure unit that equals 1,000 pascals, with pascals representing force in newtons per square meter. The two units help compare pressure levels across systems.

Conversion Formula
The formula to convert psi to kpa is: kpa = psi × 6.89476. This works because 1 psi is defined as 6.89476 kilopascals. By multiplying the psi value by this factor, you convert pounds per square inch into kilopascals. For example, 80 psi times 6.89476 yields 551.5808 kpa, which rounds to 551.6.
Conversion Example
- Convert 50 psi to kpa:
- Multiply 50 by 6.89476
- 50 × 6.89476 = 344.738
- Result: 344.738 kpa
- Convert 100 psi to kpa:
- Multiply 100 by 6.89476
- 100 × 6.89476 = 689.476
- Result: 689.476 kpa
- Convert 25 psi to kpa:
- Multiply 25 by 6.89476
- 25 × 6.89476 = 172.369
- Result: 172.369 kpa
- Convert 10 psi to kpa:
- Multiply 10 by 6.89476
- 10 × 6.89476 = 68.9476
- Result: 68.9476 kpa

Conversion Definitions
Psi
Psi, pounds per square inch, measures pressure based on force in pounds over an area of one square inch, used mainly in the US for tire pressures, hydraulics, and other pressure related measurements. It indicates how much force is applied per square inch of surface.
Kpa
Kilopascal (kpa) is a metric unit of pressure equal to 1,000 pascals, where one pascal is a force of one newton applied over an area of one square meter. It is used globally for pressure, weather, and scientific measurements to quantify force per area.
