PSI to Pascals (Pa) Converter
A multi-unit pressure converter. Enter a value in any field to instantly convert between **PSI**, **Pascals (Pa)**, **Kilopascals (kPa)**, and **Megapascals (MPa)**.
How to Convert PSI to Pascals
Converting Pounds per Square Inch (PSI) to Pascals (Pa) is a common calculation in engineering and science. The Pascal (Pa) is the SI base unit for pressure, but it is a very small unit, so **Kilopascals (kPa)** and **Megapascals (MPa)** are more frequently used.
The Conversion Formula
The exact international conversion factor is:
To convert from PSI to Pascals, you **multiply the PSI value by 6,894.757**.
- Formula:
Pa = PSI × 6894.757 - Example:
32 PSI × 6894.757 = 220,632.23 Pa
Converting to kPa and MPa
Because the Pascal value is so large, it's more practical to convert to kilopascals (1,000 Pa) or megapascals (1,000,000 Pa).
- PSI to Kilopascals (kPa):
kPa = PSI × 6.89476 - PSI to Megapascals (MPa):
MPa = PSI × 0.00689476
Using our 32 PSI example: 32 * 6.89476 = 220.63 kPa, or 0.22 MPa.
