Millimeters of Mercury to Bars Conversion
Converting Millimeters of Mercury (mmHg) to Bars (bar) is a common pressure conversion. 1 mmHg equals 0.001333 bar. For example, 100 mmHg is equal to 0.133322 bar.
Quick Reference Values
1 mmHg = 0.001333 bar. 5 mmHg = 0.006666 bar. 10 mmHg = 0.013332 bar. 25 mmHg = 0.033331 bar. 50 mmHg = 0.066661 bar. 100 mmHg = 0.133322 bar.
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 Bars?
Bars (bar) is a unit of pressure. The bar is a unit of pressure equal to exactly 100,000 pascals (Pa). It is used to measure pressure or stress and is slightly less than the standard atmospheric pressure of 101,325 Pa. The bar is not an SI unit but is accepted for use with SI by the BIPM due to its convenience in many engineering fields [bipm-si-brochure]. The bar was introduced by the Norwegian meteorologist Vilhelm Bjerknes in 1909 to simplify atmospheric pressure measurements. It gained wider recognition in the mid-20th century and was formally accepted for use with the SI by the BIPM to provide a practical unit for pressure [bipm-si-brochure]. The bar is widely used in meteorology, engineering, and automotive industries worldwide, especially in Europe and Asia. It remains common in barometric pressure readings and tire pressure specifications, although the pascal is the SI base unit [bipm-si-brochure].
Common Misspellings
People often search for this conversion using these alternate spellings: millimeter of mercury, mm hg, millimeters mercury, mmhg, millimeters of mercery, barres, barre, bars pressure. All of these refer to the Millimeters of Mercury to Bars conversion.
