The megapascal conversion selector here selects the pressure/stress measurement unit to convert to starting from megapascals (MPa). To make a conversion starting from a unit of pressure other than megapascal, simply click on the "Reset" button.
The megapascal is a unit of pressure equal to 1,000,000 pascals (1 MPa = 1,000,000 Pa), the SI derived unit of pressure.
The megapascal (MPa) is also equal to 1,000 kilopascals (kPa), or 0.001 gigapascals (GPa), or 9.86923267 atmospheres (atm), or 10 bars (bar), or 7,500.616 millimeters of mercury at 0 °C (mmHg), or 4,014.63 inches of water at 4 °C (inH2O), or 145.037 pounds per square inch (psi), or 20,885.434 pounds per square foot (psf) or 7,500.61683 torr (Torr).
The megapascal is equal to one newton per square millimeter or 1,000,000 newtons per square meter (1 MPa = 1.0 N/mm2 = 1,000,000 N/m2). The newton (N) is a unit of force in the SI while the square millimeter (mm2) and square meter (m2) are units of area in the SI.
