31.0 psi (214 kPa) is comparable to a mountain-bike or gravel-bike tire inflation pressure.

Did you know? Car tire (typical) is 230 kPa.

Most passenger cars use 200-250 kPa (29-36 psi). The correct pressure is on a sticker inside the driver's door.

How to Convert Psi to MPa

1 psi = 0.00689476 MPa

MPa = Psi × 0.00689476

Example: 31 psi × 0.00689476 = 0.21374 MPa

Reverse Conversion

To convert MPa back to psi:

  • Remember, 1 MPa equals 145.038 psi.
  • To convert 0.21374 MPa to psi, multiply 0.21374 x 145.038, resulting in 31 psi.

31 psi is also equal to:

  • 213740 pascal
  • 213.74 kPa
  • 2.1374 bar
About these units

Psi: Imperial/US customary pressure unit equal to one pound-force per square inch.

MPa: SI-derived pressure unit equal to 1,000,000 pascals (10⁶ Pa).
