Conversion Formula
The formula to convert psi to kpa is: kpa = psi × 6.89476. This works because 1 psi equals exactly 6.89476 kilopascals, a fixed conversion factor based on the relationship between pounds per square inch and the SI unit of pressure.
For example, for 8 psi: 8 × 6.89476 = 55.157 kpa. The calculation multiplies the psi value by the factor, giving the pressure in kilopascals, making it easy to switch between units for engineering or scientific purposes.
Conversion Example
- Convert 12 psi:
- Multiply 12 by 6.89476.
- 12 × 6.89476 = 82.73712.
- Result: 82.7371 kpa.
- Convert 5 psi:
- Multiply 5 by 6.89476.
- 5 × 6.89476 = 34.4738.
- Result: 34.4738 kpa.
- Convert 20 psi:
- Multiply 20 by 6.89476.
- 20 × 6.89476 = 137.8952.
- Result: 137.8952 kpa.
- Convert 0 psi:
- Multiply 0 by 6.89476.
- 0 × 6.89476 = 0.
- Result: 0 kpa.
