The conversion of 12 kpa to psi results in approximately 0.174 psi.
Table of Contents
To convert kilopascal (kpa) to pounds per square inch (psi), multiply the kpa value by 0.145038. This works because 1 kpa equals 0.145038 psi, so the calculation involves scaling the pressure from kilopascal units to psi units, ensuring the pressure measurement is accurate in different systems.
Conversion Result and Explanation
12 kpa equals about 0.174 psi, showing how small the pressure is when measured in psi compared to kpa. Since the conversion factor is less than 1, the psi value is smaller than the kpa value, reflecting the different measurement scales used in pressure units.

Conversion Formula
The formula to convert kpa to psi is multiplying the number of kilopascals by 0.145038. This is because 1 kpa equals 0.145038 psi. The calculation involves scaling the pressure measurement from kpa units to psi units. For example, for 12 kpa: 12 x 0.145038 = 1.740456 psi.
Conversion Example
- Convert 20 kpa:
- Multiply 20 by 0.145038
- 20 x 0.145038 = 2.90076 psi
- Result: 20 kpa equals approximately 2.9008 psi
- Convert 50 kpa:
- Multiply 50 by 0.145038
- 50 x 0.145038 = 7.2519 psi
- Result: 50 kpa equals approximately 7.2519 psi
- Convert 100 kpa:
- Multiply 100 by 0.145038
- 100 x 0.145038 = 14.5038 psi
- Result: 100 kpa equals about 14.5038 psi

Conversion Definitions
kpa
Kilopascal (kpa) is a metric pressure unit equal to 1000 pascals, used to measure pressure, force per unit area, in systems like weather, engineering, and physics. It is part of the International System of Units (SI) and is common in scientific contexts.
psi
Pounds per square inch (psi) is an imperial pressure unit measuring force applied over an area, mainly used in the United States for tire pressure, hydraulics, and other engineering applications. It indicates how many pounds of force are exerted in one square inch.
Conversion FAQs
Why is converting kpa to psi important in engineering?
Converting kpa to psi is vital because different regions and industries use different measurement systems. Engineers need to switch between these units to ensure safety, accuracy, and compatibility across systems and equipment, especially when dealing with international standards.
How accurate is the conversion factor of 0.145038?
The factor 0.145038 is based on precise definitions: 1 kpa equals exactly 0.145038 psi. While small decimal differences can appear, it provides a high degree of accuracy for most practical applications, ensuring pressure conversions are reliable for engineering and scientific use.
Can I use this conversion for liquids other than water?
Yes, but with caution. The conversion from kpa to psi is purely a pressure unit transformation and does not depend on the fluid. However, the pressure’s context, like in liquids or gases, affects application, but the units themselves are interchangeable regardless of the fluid involved.
