How to convert pounds per square inch to pascals
1 pound per square inch = 6,894.757293 pascals. To convert pounds per square inch to pascals, multiply by 6,894.757293. One psi is one pound-force on one square inch, exactly 6,894.757293168 Pa. The pascal is the SI unit of pressure, one newton per square meter.
Worked examples
- 1 pound per square inch = 6,894.76 Pa (1 × 6,894.7573)
- 32 pounds per square inch = 220,632 Pa (32 × 6,894.7573)
- 100 pounds per square inch = 689,476 Pa (100 × 6,894.7573)
Where this conversion comes up
Pounds per square inch are used for tire pressure, compressors and plumbing in the US; pascals for physics and sound pressure. Formulas in physics and fluid mechanics need SI pascals, while US gauges show psi. One psi is exactly 6,894.757293168 Pa (pound-force via standard gravity, divided by one square inch), so a 32 psi tire is 220,632 Pa, or 220.6 kPa.
Quick estimate
Multiply by 6,900 (0.07% high): 10 psi ≈ 69,000 Pa, exact 68,947.6 Pa.
Common mistakes
- Dividing instead of multiplying. A pascal is smaller than a pound per square inch, so the number of pascals must come out larger: 1 pound per square inch = 6,894.76 Pa.
