Conversion Definitions
The following is a list of definitions relating to conversions between megapascals and psi.
What is a megapascal (MPa)?
A megapascal is a unit of Pressure in the International System of Units (SI). The symbol for megapascal is MPa. There are 0.00689475729 megapascals in a psi.
What is pounds per square inch (psi)?
Pounds per square inch (or pound-force per square inch) is a non-SI unit of Pressure. The symbol for pounds per square inch is psi or lbf/in2. There are 145.0377 psi in a megapascal.
Conversion Formula
Let's take a closer look at the conversion formula so that you can do these conversions yourself with a calculator or with an old-fashioned pencil and paper.
The formula to convert from MPa to psi is:
psi = MPa ÷ 0.00689475729
Conversion Example
Next, let's look at an example showing the work and calculations that are involved in converting from megapascals to pounds per square inch (MPa to psi).
Megapascal to Psi Conversion Example
Task: Convert 8 megapascals to psi (show work) Formula: MPa ÷ 0.00689475729 = psi Calculations: 8 MPa ÷ 0.00689475729 = 1,160.3019 psi Result: 8 MPa is equal to 1,160.3019 psi
