Megapascal (MPa)
A megapascal is one million pascals — a scale for high-strength materials and deep industrial pressures.
Megapascals rate concrete strength, hydraulic systems, and pressures in oil and gas equipment.

About these units
Short background on the units used in this conversion.
Pound per Square Inch (psi) (psi)
Pounds per square inch (psi) measures force in pounds distributed over each square inch of area.
PSI is the default for US tire pressure, HVAC systems, hydraulics, and many industrial pressure ratings.
