Quick Reference Values
1 psi = 0.006895 MPa. 5 psi = 0.034474 MPa. 10 psi = 0.068948 MPa. 25 psi = 0.172369 MPa. 50 psi = 0.344738 MPa. 100 psi = 0.689476 MPa.
What is Pounds per Square Inch?
Pounds per Square Inch (psi) is a unit of pressure. Pounds per square inch (psi) measures pressure as force in pounds applied over one square inch of area. It is defined as 1 psi = 6,894.76 pascals in the SI unit system [nist-si-guide]. Psi originated in English-speaking countries for engineering and industrial applications during the 19th century, formalized through American standards for pressure measurement [nist-si-guide]. Psi remains common in the United States, Canada, and the UK for tire pressure, hydraulic systems, and HVAC industries. It is also referenced in international engineering standards [nist-sp-811].
What is Megapascals?
Megapascals (MPa) is a unit of pressure. The megapascal (MPa) equals one million pascals (Pa), the SI derived unit for pressure. It measures force per unit area, with 1 MPa equaling 1,000,000 N/m². The pascal is defined by the BIPM as one newton per square meter, making the megapascal a standard for high-pressure measurements in engineering and materials science[bipm-si-brochure]. The pascal unit was adopted by the CGPM in 1971, named after Blaise Pascal to honor his work in hydrostatics. The megapascal as a multiple of the pascal emerged with the widespread use of the SI system to quantify large pressure values in the 20th century[bipm-si-brochure]. Megapascals are widely used globally in engineering, construction, and materials testing. Countries adopting the metric system, including those in Europe and Asia, rely on MPa for tensile strength and pressure measurements. The ISO 80000 standard references MPa for expressing pressure in technical documentation[iso-80000].
Common Misspellings
People often search for this conversion using these alternate spellings: pounds per square inch, pound per sq inch, psiin, mega pascal, megapascel, megapascal, megapascall, megapascal. All of these refer to the Pounds per Square Inch to Megapascals conversion.
