Home All Definitions Unit Megapascal ( MPa ) Unit Definition Megapascal ( MPa ) Unit Definition The megapascal is a multiple of the unit pascal (Pa) for pressure. The International System of Units (SI) defines the prefix mega (M) as a factor of one million or 10⁶ or 1000000. Per this definition, one megapascal is 10⁶ pascals. The megapascal is represented by the symbol MPa . SI Multiples A table of various pressure pascal (Pa) units derived from SI multiples: MPa , or megapascal, is a pressure unit in the International System of Units (SI), defined as one million pascals (Pa). The conversion indicates that 1 MPa equals 1, 000, 000 Pa or 1, 000 kPa.
