PSI (Pounds per Square Inch) and kPa (Kilopascal) are both units of pressure commonly used in various applications. PSI is more common in the United States and some other countries, while kPa is part of the metric system and is used internationally.
To convert between PSI and kPa, use these formulas:
• 1 PSI = 6.89476 kPa
• 1 kPa = 0.145038 PSI
| PSI | kPa |
|---|---|
| 1 | 6.89476 |
| 5 | 34.4738 |
| 10 | 68.9476 |
| 15 | 103.421 |
| 20 | 137.895 |
To convert PSI to kPa, multiply the PSI value by 6.89476.
Example: Convert 25 PSI to kPa
25 PSI × 6.89476 = 172.369 kPa
To convert kPa to PSI, multiply the kPa value by 0.145038.
Example: Convert 200 kPa to PSI
200 kPa × 0.145038 = 29.01 PSI
These pressure units are commonly used in:
• Tire pressure measurement
• Industrial processes
• HVAC systems
• Hydraulic systems
• Scientific research
