Explanation

megapascals and pounds per square inch are units of pressure. They are used in common measurement contexts. Which one you use depends on the unit system or industry. They are defined at different scales, so the factor is not 1: 1 megapascals = 145.0377377302 pounds per square inch, and 1 pounds per square inch = 0.0068947573 megapascals. Because one pounds per square inch represents a smaller amount than one megapascals, the numeric value gets larger in this direction.

How to convert megapascals to pounds per square inch

  1. Enter the value in megapascals (MPa).
  2. Multiply it by 145.0377377302.
  3. The result is the equivalent value in pounds per square inch (psi).
  4. Round the result if needed.

Worked example

9781 × 145.0377377302 = 1418614.11273925 pounds per square inch

Frequently Asked Questions
