Here's how to convert pounds per square inch (psi) to Newtons per square meter (N/m² or Pascals, Pa):

Conversion Factor:

* 1 psi = 6894.76 N/m²

Calculation:

1. Multiply psi by the conversion factor: 30 psi * 6894.76 N/m²/psi = 206,842.8 N/m²

Therefore, 30 psi is equal to 206,842.8 N/m² or Pascals (Pa).
