120 psi equals approximately 827.4 kpa
Converting 120 psi to kpa results in about 827.4 kpa. This conversion is simple because 1 psi equals 6.8947 kpa, so multiplying 120 by this factor gives the value in kilopascals.
Conversion from psi to kpa
The process involves multiplying the pressure value in pounds per square inch (psi) by the conversion factor 6.8947. This factor stems from the relationship between these units, where 1 psi is exactly equal to 6.8947 kpa. For example, 120 psi times 6.8947 yields 827.364 kpa, which rounds to 827.4 kpa.

Conversion Formula
The conversion formula multiplies psi by 6.8947, which is the exact factor between psi and kpa. This works because PSI and KPA are pressure units, and 1 psi equals 6.8947 kpa. For example, converting 50 psi: 50 x 6.8947 = 344.735 kpa.
Conversion Example
- Convert 50 psi:
- Multiply 50 by 6.8947
- 50 x 6.8947 = 344.735
- Result is 344.735 kpa
- Convert 200 psi:
- Multiply 200 by 6.8947
- 200 x 6.8947 = 1378.94
- Result is 1378.94 kpa
- Convert 100 psi:
- Multiply 100 by 6.8947
- 100 x 6.8947 = 689.47
- Result is 689.47 kpa
- Convert 75 psi:
- Multiply 75 by 6.8947
- 75 x 6.8947 = 517.1025
- Result is 517.1025 kpa
- Convert 10 psi:
- Multiply 10 by 6.8947
- 10 x 6.8947 = 68.947
- Result is 68.947 kpa

Conversion Definitions
psi
Psi measures pressure, indicating force per unit area, specifically pounds-force per square inch. It is used mainly in the US for tire pressure, hydraulics, and other pressure measurements, and helps quantify the force exerted on a surface.
kpa
Kilopascal (kpa) is a metric pressure unit, where 1 kpa equals 1000 pascals. It is used worldwide in science, weather reports, and engineering to measure pressure, representing the force applied over an area in kilonewtons per square meter.
Conversion FAQs
What does 120 psi convert to in pascals?
Since 1 psi equals 6894.7 pascals, 120 psi equals 120 x 6894.7 = 827,364 pascals, or approximately 827.4 kpa.
Is converting psi to kpa accurate using the factor 6.8947?
Yes, because 6.8947 is the exact conversion factor between psi and kpa, based on the definition of these units, ensuring precise calculations when multiplying psi by this factor.
Why use kpa instead of psi in some measurements?
Kpa is part of the metric system, which is used globally, making it more compatible with scientific calculations, international standards, and data sharing across different countries and industries.
Can I convert pressure values from kpa back to psi?
Yes, by dividing the kpa value by 6.8947, you can revert to psi. For example, 827.4 kpa divided by 6.8947 equals approximately 120 psi.
What tools are best for converting psi to kpa?
