psi to MPa

psi

• Definition: psi stands for pounds per square inch, a unit of pressure that measures the force exerted on one square inch of surface area.

• Symbol: The symbol for psi is “psi”.

• Usage: psi is commonly used in the United States to measure tire pressure, as well as in various industrial applications to indicate pressure levels.

megapascal

• Definition: A megapascal (MPa) is a unit of pressure equal to one million pascals, where a pascal is defined as one newton per square meter.

• Symbol: The symbol for megapascal is “MPa”.

• Usage: Megapascals are frequently used in engineering and scientific contexts, particularly in materials testing and structural analysis.

Origin of the psi

• The term psi originated in the United States, combining the imperial unit of pounds with the concept of area measured in square inches. It has been widely adopted in various fields, particularly in automotive and manufacturing sectors.

Origin of the megapascal

• The megapascal derives from the pascal, named after the French mathematician and physicist Blaise Pascal. The prefix “mega” denotes a factor of one million, making the megapascal a convenient unit for expressing high pressures.
