Conversion Formula
The formula to convert kPa to psi is: psi = kPa × 0.145038. This works because the conversion factor 0.145038 is derived from the exact relationship between the units. It reflects how many pounds per square inch equal one kilopascal. For example, converting 10 kPa involves multiplying 10 by 0.145038, yielding 1.45038 psi.
Conversion Example
- Convert 50 kPa to psi:
- Step 1: Take the value 50 kPa.
- Step 2: Multiply 50 by 0.145038.
- Step 3: 50 × 0.145038 = 7.2519 psi.
- Result: 50 kPa equals approximately 7.2519 psi.
- Convert 100 kPa to psi:
- Step 1: Take 100 kPa.
- Step 2: Multiply 100 by 0.145038.
- Step 3: 100 × 0.145038 = 14.5038 psi.
- Result: 100 kPa equals approximately 14.5038 psi.
- Convert 5 kPa to psi:
- Step 1: Take 5 kPa.
- Step 2: Multiply 5 by 0.145038.
- Step 3: 5 × 0.145038 = 0.7252 psi.
- Result: 5 kPa equals approximately 0.7252 psi.

Conversion Definitions
kpa (kilopascal) is a metric unit measuring pressure, with 1 kPa equal to 1000 pascals, representing force per area. It is used worldwide in engineering, weather, and physics to quantify pressure, stress, or load on surfaces in scientific and industrial contexts.
psi (pounds per square inch) is a pressure unit in the imperial system, indicating how many pounds of force are exerted over one square inch of area. It is common in the United States for measuring tire pressure, hydraulics, and other pressure-dependent systems.
Conversion FAQs
How precise is the 0.145038 factor for converting kPa to psi?
The 0.145038 factor is an exact conversion constant based on the relationship between the pascal and pound-force per square inch units. It provides high precision for most practical purposes, but in highly sensitive scientific calculations, more decimal places may be needed.
Can I convert kPa to psi without a calculator?
Yes, by using the conversion factor 0.145038, you can multiply the kPa value by this number manually or estimate it for quick calculations. For example, 20 kPa times 0.15 gives a rough estimate of 3 psi, close enough for most non-critical uses.
Why do different sources sometimes give slightly different conversion factors?
Variations occur because of rounding differences, measurement standards, or slight discrepancies in the exact definitions of units. The value 0.145038 is precise, but some sources may use rounded or approximate factors for simplicity, leading to minor differences.
