Megapascals (MPa)
Definition
A megapascal (MPa) is a unit of pressure equal to 1,000,000 pascals or 1,000 kilopascals. It is used for expressing very high pressures.
History
The megapascal became the standard unit for material science and structural engineering as SI units spread globally. It replaced older units like kgf/cm² in many engineering specifications.
Current use
Megapascals are the standard unit for expressing tensile strength, yield strength, and compressive strength of materials. Concrete, steel, and composite material specifications use MPa worldwide.
Pounds per Square Inch (psi)
Definition
Pounds per square inch (psi) is an imperial unit of pressure equal to the force of one pound-force applied to an area of one square inch. It equals approximately 6,894.76 pascals.
History
PSI evolved from the British imperial system and became the dominant pressure unit in American and British engineering. It gained widespread use with the industrialization of pneumatic and hydraulic systems.
Current use
PSI is the primary pressure unit in the United States for tire pressure, water pressure, hydraulic systems, compressed gas cylinders, and HVAC systems. It is also widely used in oil and gas industries.
