The conversion of 80 psi equals approximately 550.4 kpa. This means that when pressure is 80 pounds per square inch, it is equivalent to about 550.4 kilopascals.
To convert psi to kpa, multiply the psi value by 6.89476. This conversion factor comes from the fact that 1 psi equals exactly 6.89476 kpa. Therefore, by multiplying, you switch from pounds per square inch to kilopascals, a metric pressure unit.

Conversion Formula
The formula to convert psi to kpa is: kpa = psi × 6.89476. This works because 1 psi, or pounds per square inch, is defined as exactly 6.89476 kilopascals. By multiplying psi by this factor, you directly convert from imperial to metric pressure units. For example, if you have 80 psi, multiply 80 by 6.89476 to get 551.1808 kpa.
Conversion Example
- Convert 50 psi to kpa:
- Start with 50 psi.

Conversion Definitions
psi
Psi, or pounds per square inch, measures pressure by indicating how many pounds of force are applied to one square inch of area. It is used mainly in the United States for measuring tire pressure, fluid pressure, and other industrial and mechanical applications.
kpa
Kilopascal, abbreviated as kpa, is a metric unit of pressure equal to 1,000 pascals. It is used worldwide to quantify pressure in various fields, including meteorology, engineering, and physics, providing a standardized way to measure force per unit area.
