Conversion Formula
The formula for converting psi to kpa is: kpa = psi × 6.89476. This works because 1 psi equals 6.89476 kilopascals, derived from the relation 1 pound-force per square inch equals 6.89476 kilopascals. Multiplying the psi value by this factor gives the pressure in kpa. For example, for 4 psi: 4 × 6.89476 = 27.57904 kpa.
Conversion Example
- Convert 7 psi to kpa:
- Multiply 7 by 6.89476: 7 × 6.89476 = 48.26232 kpa.
- Result: 7 psi equals approximately 48.2623 kpa.
- Convert 10 psi to kpa:
- Multiply 10 by 6.89476: 10 × 6.89476 = 68.9476 kpa.
- Result: 10 psi equals approximately 68.9476 kpa.
- Convert 1 psi to kpa:
- Multiply 1 by 6.89476: 1 × 6.89476 = 6.89476 kpa.
- Result: 1 psi equals approximately 6.8948 kpa.
- Convert 15 psi to kpa:
- Multiply 15 by 6.89476: 15 × 6.89476 = 103.4214 kpa.
- Result: 15 psi equals approximately 103.4214 kpa.

Conversion Definitions
psi
Psi (pounds per square inch) measures pressure by indicating how many pounds-force applied over one inch squared area. It’s widely used in the US for tire, fluid, and gas pressures, and relates to force over a specific surface area.
kpa
Kilopascal (kpa) measures pressure in terms of force (newtons) over an area of one square meter. It’s part of the metric system, used internationally for scientific and engineering pressure measurements, where 1 kpa equals 1000 pascals.
Conversion FAQs
What is the easiest way to convert 4 psi to kpa manually?
You multiply 4 by 6.89476, which is the fixed conversion factor, resulting in approximately 27.58 kpa. This straightforward calculation gives you the pressure in kilopascals without needing a calculator or tool.
Can I convert psi to kpa with a calculator or do I need special equipment?
A simple calculator is enough since the conversion involves multiplying by 6.89476. No special equipment is needed, just input the psi value and multiply to get the kpa measurement.
Is the conversion from psi to kpa accurate enough for scientific experiments?
Yes, because 6.89476 is an exact conversion factor, the result is precise for all practical purposes, including scientific and engineering use. However, always consider measurement device accuracy for critical applications.
If I have a pressure reading in psi, can I trust the conversion to kpa?
Yes, as long as the psi reading is accurate, multiplying it by 6.89476 will give a reliable kpa value. Always verify your pressure gauge calibration to ensure correct measurements.
