Converting 8 psi results in approximately 55.16 kpa.
To convert psi to kpa, multiply the psi value by 6.89476, because 1 psi equals 6.89476 kilopascals. This conversion works because psi and kpa are both units measuring pressure, with psi being pounds per square inch and kpa being kilopascals. So, 8 psi times 6.89476 equals 55.15808 kpa, which rounds to 55.16 kpa.

Conversion Formula
The formula to convert psi to kpa is: kpa = psi * 6.89476. This works because 1 psi equals 6.89476 kilopascals, based on the pressure units’ relationship. For example, if you multiply 8 psi by 6.89476, you get 55.15808 kpa, showing how the units relate mathematically.
Conversion Example
- Convert 12 psi:
- Multiply 12 by 6.89476
- 12 * 6.89476 = 82.73712 kpa
- The pressure in kpa is 82.7371
- Convert 5 psi:
- Multiply 5 by 6.89476
- 5 * 6.89476 = 34.4738 kpa
- The pressure in kpa is 34.4738
- Convert 20 psi:
- Multiply 20 by 6.89476
- 20 * 6.89476 = 137.8952 kpa
- The pressure in kpa is 137.8952
- Convert 0 psi:
- Multiply 0 by 6.89476
- 0 * 6.89476 = 0 kpa
- The pressure in kpa is 0

Conversion Definitions
Psi (pounds per square inch) measures pressure based on pounds force exerted over one square inch area, used mainly in the US for tire pressure and other applications. It quantifies force per unit area, with one psi equal to 6894.76 pascals.
Kilopascal (kpa) is a metric pressure unit representing thousands of pascals, the SI derived unit of pressure. It is used to measure force per unit area, with 1 kpa equals 1000 pascals, often used in engineering and meteorology for pressure readings.
Conversion FAQs
How accurate is the conversion from psi to kpa?
The conversion uses a fixed factor of 6.89476, which is precise for standard pressure conversions. Minor rounding differences can occur with decimal places, but overall, it provides reliable results for practical purposes.
Can I convert psi to kpa without a calculator?
Yes, by multiplying the psi value by 6.89476, you can convert pressure units manually. For quick estimates, approximate 6.9 as the factor, but for exact calculations, use the precise number or a calculator.
Are there other units I can convert psi into?
Yes, psi can convert into bars, atmospheres, or pascals. For example, 1 psi equals 0.06895 bar or 0.068 atm, and as shown, 8 psi equals 55.16 kpa. Conversion depends on the required unit and context of use.
Why is psi used more in some countries and kpa in others?
Psi is primarily used in the US due to historical measurement preferences, while kpa is part of the metric system, adopted in most other countries for scientific and engineering measurements. Both units measure pressure but cater to different standards.
