Millibars to Millimeters of Mercury Conversion
Converting Millibars (mbar) to Millimeters of Mercury (mmHg) is a common pressure conversion. 1 mbar equals 0.750064 mmHg. For example, 100 mbar is equal to 75.006376 mmHg.
Quick Reference Values
1 mbar = 0.750064 mmHg. 5 mbar = 3.750319 mmHg. 10 mbar = 7.500638 mmHg. 25 mbar = 18.751594 mmHg. 50 mbar = 37.503188 mmHg. 100 mbar = 75.006376 mmHg.
What is Millibars?
Millibars (mbar) is a unit of pressure. The millibar is a unit of pressure equal to 100 pascals or 0.1 kilopascals. It is one-thousandth of a bar, which is defined as exactly 100,000 pascals in the International System of Units (SI). The millibar is commonly used in meteorology to measure atmospheric pressure and is recognized under ISO standards for pressure units [iso-80000]. The bar and its subunit, the millibar, were introduced by the German meteorologist Heinrich von Helmholtz in the early 20th century. The millibar was adopted as a practical unit for meteorological pressure measurements before SI units were formalized [nist-sp-811]. Millibars remain widely used in weather reports and aviation worldwide, especially in countries like the United States, United Kingdom, and Australia. Meteorological agencies, including NOAA and the UK Met Office, use millibars alongside pascals for atmospheric pressure [nist-sp-811].
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: milibars, milibars, millibar, milibar, millimeter of mercury, mm hg, millimeters mercury, mmhg, millimeters of mercery. All of these refer to the Millibars to Millimeters of Mercury conversion.
