Understanding Megapascal and Pound per Square Inch

Megapascal (MPa)

The megapascal is a unit of pressure in the SI system.

• 1 MPa = 1,000,000 pascals

• 1 MPa = 145.038 PSI

• Used for high-pressure systems

• Common in engineering and materials

Pound per Square Inch (psi)

The pound per square inch is a unit of pressure in the Imperial system.

• 1 PSI = 6.89476 kPa

• Standard for US tire pressure

• Used in scuba diving tanks

• Common in automotive industry

SI to Imperial Conversion

You are converting from a si unit to a imperial unit. This is a common conversion needed when:

  • Working with international equipment specifications
  • Using tools or vehicles from different countries
  • Following international standards and regulations
  • Collaborating on international projects
  • Converting medical or scientific data

Practical Examples

Everyday Use
Professional Use
  • • Material tensile strength (500 MPa) = 72,519 PSI
  • • Hydraulic press (70 MPa) = 10,152 PSI
  • • Industrial boiler (10 MPa) = 1,450 PSI
