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:

1 PSI = 6,894.75729 Pascals (Pa)

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.
