12 kpa is approximately 0.174 psi.
To convert kilopascals (kpa) to pounds per square inch (psi), you multiply the kpa value by 0.145038. This conversion works because 1 kilopascal equals 0.145038 pounds per square inch, allowing us to switch between these two pressure measurement units accurately.

Conversion Formula
The conversion from kpa to psi is based on the ratio 1 kpa = 0.145038 psi. This formula works because pressure units are related through their definitions: 1 kilopascal equals 1,000 pascals, and 1 psi equals 6894.76 pascals, so dividing gives the ratio. For example, to convert 12 kpa:
- Multiply 12 by 0.145038
- 12 × 0.145038 = 1.740456
- Result: approximately 1.7405 psi
Conversion Example
Suppose you want convert 25 kpa to psi. Here’s how you do it:
- Start with 25 kpa.
- Apply the formula: 25 × 0.145038.
- Calculate: 25 × 0.145038 = 3.62595.
- Answer: 25 kpa equals approximately 3.626 psi.

Conversion Definitions
kpa
Kilopascal (kpa) is a pressure measurement unit equal to 1,000 pascals, where pascals are the SI derived unit for pressure, defined as one newton per square meter. It is used in meteorology, engineering, and various scientific fields to measure force applied over an area.
psi
Pounds per square inch (psi) is a pressure unit measuring force in pounds applied over an area of one square inch. Commonly used in the United States for tire pressures, hydraulics, and plumbing, it relates force to area in imperial measurement systems.
Conversion FAQs
How accurate is converting 12 kpa to psi using the formula?
The conversion based on multiplying by 0.145038 provides high accuracy as it is derived from the exact relationship between pascals and pounds per square inch. Slight rounding differences may occur in decimal places but overall the result is precise enough for most uses.
Can I use this formula for converting other pressure units?
This specific formula only converts kpa to psi. For other units like bar or atm, different conversion factors are needed. Always check the appropriate ratios for the units involved to ensure accuracy.
Why does pressure measurement vary in different units?
Pressure varies depending on measurement systems and regions. Metric units like kpa are standard internationally, while psi is used mainly in the US. Different units suit different industries or scientific purposes, leading to the need for conversions.
Is the conversion factor affected by temperature?
No, the conversion factor between kpa and psi is a ratio of units and does not depend on temperature. However, actual pressure readings can vary with temperature changes, but the unit conversion remains constant.
