You can do the reverse unit conversion from millimeter mercury to megapascal, or enter any two units below:
megapascal to torr
megapascal to kip/square inch
megapascal to millimeter water
megapascal to micrometer of water
megapascal to ton/square meter
megapascal to pound/square inch
megapascal to centimeter of mercury
megapascal to attobar
megapascal to yottabar
megapascal to picobar
The SI prefix "mega" represents a factor of 106, or in exponential notation, 1E6.
So 1 megapascal = 106 pascals.
The definition of a pascal is as follows:
The pascal (symbol Pa) is the SI unit of pressure.It is equivalent to one newton per square metre. The unit is named after Blaise Pascal, the eminent French mathematician, physicist and philosopher.
The millimeter of mercury by definition is 133.322387415 Pa (13.5951 g/cm3 × 9.80665 m/s2 × 1 mm), which is approximated with known accuracies of density of mercury and standard gravity.
The torr is defined as 1/760 of one standard atmosphere, while the atmosphere is defined as 101325 pascals. Therefore, 1 Torr is equal to
101325/760 Pa. The decimal form of this fraction is approximately 133.322368421.
The relationship between the torr and the millimeter of mercury is:
1 Torr = 0.999999857533699 mmHg
1 mmHg = 1.000000142466321 Torr
The difference between one millimeter of mercury and one torr, as well as between one atmosphere (101.325 kPa) and 760 mmHg (101.3250144354 kPa), is less than one part in seven million (or less than 0.000015%). This small difference is negligible for most applications outside metrology.
