Our MPa to psi conversion tool is a simple tool that will help you convert pressure (or stress) from megapascals (MPa) to pounds per square inch (psi) or vice versa. You can even use it to convert pressure to other units!

In the following article, we shall learn the pressure conversion from MPa to psi with an example to help you digest this concept.

MPa to psi conversion

Megapascal (MPa) is a decimal multiple unit of pascal (Pa), the SI unit of pressure, stress, Young's Modulus, and strength.

1 MPa=106 Pa\rm 1 \text{ } MPa = \rm 10^6\text{ } Pa

Pounds per square inch, or psi (lbf/in2), is a unit of pressure and stress. The "pound" in psi is pound-force (lbf), a unit of force, and not pound-mass, a unit of mass.

1 lbf/in2=6894.76 Pa1 \text{ lbf/in}^2 = 6894.76 \text{ Pa}

The conversion rate between megapascals and psi is:

1 MPa=145.0377 lbf/in21 lbf/in2=0.00689476 MPa\begin{align*} \rm 1 \text{ } MPa &= \rm 145.0377 \text{ }lbf/in^2 \\ \rm 1 \text{ }lbf/in^2 &=\rm 0.00689476 \text{ } MPa \end{align*}

Example calculation: MPa to psi

Say the pressure in a system is 22 MPa. In psi, this pressure would be:

1 MPa=145.03771 lbf/in2  ⟹  22 MPa=22×145.0377 lbf/in2=3190.83 lbf/in2\begin{align*} \rm 1 \text{ } MPa &= \rm 145.0377 1 \text{ }lbf/in^2 \\ \implies \rm 22 \text{ } MPa &= \rm 22 \times 145.0377 \text{ }lbf/in^2 \\ &= \rm 3190.83 \text{ }lbf/in^2 \end{align*}

In another system, the pressure is 150 psi. This pressure in Mpa is:

1 lbf/in2=0.00689476 MPa  ⟹  150 lbf/in2=150×0.00689476 MPa=1.034214 MPa\begin{align*} \rm 1 \text{ }lbf/in^2 &=\rm 0.00689476 \text{ } MPa\\ \implies \rm 150 \text{ }lbf/in^2 &=\rm 150 \times 0.00689476 \text{ } MPa\\ &= \rm 1.034214 \text{ } MPa \end{align*}

FAQs

How do you convert pressure from megapascals to pounds per square inch?

To convert pressure from megapascals (MPa) to pounds per square inch (lbf/in2), follow these steps:

  1. Find the unit conversion rate from megapascals to psi:
    1 MPa = 145.0377 lbf/in2.

  2. Multiply the pressure in MPa with 145.0377 lbf/in2/MPa to convert megapascals into psi:
    pressure in lbf/in2 = pressure in MPa × 145.0377 lbf/in2/MPa.

  3. Verify the result with our MPa to psi pressure conversion tool.

What is 240 psi in megapascals?

240 psi pressure is equal to 1.654742 megapascals, approximately 1.66 MPa. To obtain this answer, follow these steps:

  1. Find the unit conversion rate from bars to hectopascals:
    1 lbf/in2 = 0.00689476 MPa.

  2. Multiply the pressure in psi with 0.00689476 MPa/lbf/in2 to convert psi into megapascals:
    pressure in MPa = 240 × 0.00689476 = 1.6547424 ≈1.66 MPa.

  3. Verify the result with our MPa to psi conversion tool.
