About the units
Megapascal (MPa)
One million pascals, used for material strength.
Pound per square inch (psi)
About 6.895 kilopascals, the usual unit for US tire pressure.
Pressure is force per unit area. The SI unit is the pascal, one newton per square meter. Tire pressures are given in psi or bar, weather in hectopascals or millibars, and blood pressure in millimeters of mercury.
