Convert MPa To PSI: Mega Pascal To PSI Calculator + Conversion Chart

When using pressure units, we usually use either MPa or PSI. That is because Pa (Pascal) is a very small unit compared to PSI. To help everybody convert MPa to PSI, we have designed a simple-to-use MPa to PSI calculator (insert MPA, get PSI) as well as a conversion chart with 0.01 MPa to 100,000 MPa converted to PSI.

Let’s first check what MPa and PSI are and how to convert MPa to PSI using a pocket calculator:

  • MPa or MegaPascal is a metric unit of pressure equal to 1,000,000 Pa. 1 Pa or Pascal is a pressure that a force of 1 Newton makes on 1 square meter. Million Pascals or MPa is hence a pressure that 1,000,000 Netwons make on 1 square meter of surface area (1 MPa = 1,000,000 N/m2). Because we are using millions of Pascals, MPa is a bigger unit of pressure than PSI.
  • PSI or Pounds per Square Inch is a unit of pressure used in the US and the UK. 1 PSI is a pressure that a force of 1 pound (pound-force) exerts on 1 square inch of surface area (1 PSI = 1 lbn/in2). Compared to MPa, PSI is a smaller unit of pressure.

How to convert MPa to PSI?

Easy. To convert megapascals to pounds per square inch, you only need to know 1 conversion rule:

1 MPa = 145.038 PSI

Basically, 1 MPa is equal to 145.038 PSI. For quick conversion, you can use 1 MPa is equal to 145 PSI approximation (you will make less than 0.03% conversion error). To convert MPa to PSI, you simply need to multiply the number of MPA by 145.038 (calculator below does this automatically):

Example 1: How many PSI is 25 MPa? Here is how you can calculate that:

25 MPa × 145.038 = 3,625.95 PSI

25 MPa is equal to 3,625.95 PSI.

Example 2: How many PSI is 10 MPa? Here is how you can calculate that:

10 MPa × 145.038 = 1,450.38 PSI

10 MPa is equal to 1,450.38 PSI.

Example 3: How many PSI is 1.5 MPa? Here is how you can calculate that:

1.5 MPa × 145.038 = 217.557 PSI

1.5 MPa is equal to 217.557 PSI.

As you can see, converting MPa to PSI is quite easy. You can do it with a pocket calculator. To make things simpler still, you can use the following MPa to PSI calculator and consult the conversion chart below the calculator:

As you can see, this calculator automatically converts megapascals to PSI. Let’s say you want to convert 30 MPa to PSI. Just insert ’30’ and you get the result: 30 MPa is equal to 4,351.14 PSI.

Here is the MPa to PSI conversion chart for common conversions:
