12 kpa is approximately 0.00174 psi.
To convert kilopascals (kpa) to pounds per square inch (psi), multiply the pressure value in kpa by 0.1450377. This conversion is based on the fact that 1 kpa equals 0.1450377 psi, making it easy to switch between these units for pressure measurements.
Conversion Result and Explanation
When converting 12 kpa to psi, multiplying 12 by 0.1450377 gives about 1.74045 psi. This means that 12 kilopascals is equivalent to roughly 1.74 pounds per square inch, a common conversion in fields like engineering and physics where pressure units are often interchanged.

Conversion Formula
The formula to convert kpa to psi is: psi = kpa * 0.1450377. This works because 1 kilopascal equals 0.1450377 pounds per square inch. So, to find psi, you simply multiply the kpa value by this factor. For example, 12 kpa times 0.1450377 equals approximately 1.74 psi.
Conversion Example
- Convert 20 kpa to psi:
- Multiply 20 by 0.1450377.
- 20 × 0.1450377 = 2.900754 psi.
- Result: approximately 2.9008 psi.
- Convert 50 kpa to psi:
- Multiply 50 by 0.1450377.
- 50 × 0.1450377 = 7.251885 psi.
- Result: approximately 7.2519 psi.
- Convert 100 kpa to psi:
- Multiply 100 by 0.1450377.
- 100 × 0.1450377 = 14.50377 psi.
- Result: approximately 14.5038 psi.

Conversion Definitions
kpa
Kilopascal (kpa) is a metric pressure unit equal to 1,000 pascals, measuring force per unit area, used in engineering, meteorology, and physics for expressing pressures like weather or mechanical systems.
psi
Pounds per square inch (psi) is a pressure measurement unit that indicates force in pounds applied over an area of one square inch, widely used in the United States for tire pressure, hydraulics, and industrial applications.
Conversion FAQs
What does 12 kpa mean in terms of tire pressure?
12 kpa in tire pressure translates to about 1.74 psi, which is quite low and typically not sufficient for standard vehicle tires. It might be relevant for small equipment or specific industrial applications requiring low-pressure measurements.
Why is the conversion factor from kpa to psi 0.1450377?
This factor comes from the exact relationship between the pascal and the pound-force per square inch, where 1 pascal equals approximately 0.0001450377 psi. Multiplying by this converts pressure units accurately.
Can I convert kpa to psi manually without calculator?
Yes, but it involves multiplying the kpa value by 0.1450377, which can be approximated as 0.145 for quick estimates. For precise results, a calculator or the conversion tool is recommended.
Is the conversion from kpa to psi linear?
Yes, the conversion is linear because both units measure pressure, and the conversion factor remains constant across all values, making calculations straightforward and proportional.
