Bars to Millimeters of Mercury Conversion
Converting Bars (bar) to Millimeters of Mercury (mmHg) is a common pressure conversion. 1 bar equals 750.063755 mmHg. For example, 100 bar is equal to 75,006.375542 mmHg.
Quick Mental Math: Bars to Millimeters of Mercury
Pressure units (atm, bar, psi, pascal) are diverse; use atmospheres as a reference tier.
Why is converting Bars to Millimeters of Mercury tricky?
Magnitude or direction confusion between bars and millimeters-of-mercury is the primary error source.
Quick Reference Values
1 bar = 750.063755 mmHg. 5 bar = 3,750.318777 mmHg. 10 bar = 7,500.637554 mmHg. 25 bar = 18,751.593885 mmHg. 50 bar = 37,503.187771 mmHg. 100 bar = 75,006.375542 mmHg.
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].
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].
Common Misspellings
People often search for this conversion using these alternate spellings: barres, barre, bars pressure, millimeter of mercury, mm hg, millimeters mercury, mmhg, millimeters of mercery. All of these refer to the Bars to Millimeters of Mercury conversion.
