Millimeters of Mercury to Megapascals Conversion
Converting Millimeters of Mercury (mmHg) to Megapascals (MPa) is a common pressure conversion. 1 mmHg equals 0.000133 MPa. For example, 100 mmHg is equal to 0.013332 MPa.
Quick Reference Values
1 mmHg = 0.000133 MPa. 5 mmHg = 0.000667 MPa. 10 mmHg = 0.001333 MPa. 25 mmHg = 0.003333 MPa. 50 mmHg = 0.006666 MPa. 100 mmHg = 0.013332 MPa.
What is Millimeters of Mercury?
Millimeters of Mercury (mmHg) is a unit of pressure. Millimeters of mercury (mmHg) measure pressure based on a column of mercury 1 millimeter high. It equals exactly 133.322387415 pascals, the SI derived unit for pressure, as defined by international standards. This unit is widely used in medical and meteorological fields for blood pressure and barometric pressure readings [nist-si-guide]. The mmHg unit originated from the mercury barometer invented by Evangelista Torricelli in 1643. It became standardized as a pressure unit because mercury's density allowed precise atmospheric pressure measurements. The adoption of the exact pascal conversion was formalized by the BIPM in the 20th century [bipm-si-brochure]. Millimeters of mercury remain common in healthcare worldwide, especially for blood pressure monitoring in the US and Europe. Meteorologists also use mmHg in weather reporting, though pascals are preferred in scientific contexts. Regulatory standards by ISO and NIST recognize mmHg for specific applications [nist-sp-811].
What is Megapascals?
Megapascals (MPa) is a unit of pressure. The megapascal (MPa) equals one million pascals (Pa), the SI derived unit for pressure. It measures force per unit area, with 1 MPa equaling 1,000,000 N/m². The pascal is defined by the BIPM as one newton per square meter, making the megapascal a standard for high-pressure measurements in engineering and materials science[bipm-si-brochure]. The pascal unit was adopted by the CGPM in 1971, named after Blaise Pascal to honor his work in hydrostatics. The megapascal as a multiple of the pascal emerged with the widespread use of the SI system to quantify large pressure values in the 20th century[bipm-si-brochure]. Megapascals are widely used globally in engineering, construction, and materials testing. Countries adopting the metric system, including those in Europe and Asia, rely on MPa for tensile strength and pressure measurements. The ISO 80000 standard references MPa for expressing pressure in technical documentation[iso-80000].
Common Misspellings
People often search for this conversion using these alternate spellings: millimeter of mercury, mm hg, millimeters mercury, mmhg, millimeters of mercery, mega pascal, megapascel, megapascal, megapascall, megapascal. All of these refer to the Millimeters of Mercury to Megapascals conversion.
