PSI to Kilopascals: imperial pressure in metric units
When you have a pressure reading in PSI and need kilopascals, this converter helps with international specs, scientific work, and metric-based regulations.
Formula
The formula is kPa = psi × 6.89476. Multiply PSI by 6.89476 to get kilopascals.
Worked example
30 PSI = 30 × 6.89476 = 206.84 kPa. This is a standard tire pressure recommendation.
Common Reference Values
| Pounds per Square Inch | Kilopascals | Context |
|---|---|---|
| 14.7 psi | 101.35 kPa | 14.7 psi |
| 30 psi | 206.84 kPa | 30 psi |
| 50 psi | 344.74 kPa | 50 psi |
Practical guidance
Scientific and engineering standards
Research papers and international standards often use kPa. Converting from PSI ensures your calculations align with the units used in technical literature.
Regulatory compliance
Some jurisdictions require pressure ratings in kPa for safety certifications. Converting ensures your equipment meets local requirements.
Mistake: multiplying by 7
Multiplying by 7 gives 210 kPa for 30 PSI instead of 206.84. Use 6.89476 for accuracy.
