Millibars to Inches of Mercury Conversion
Converting Millibars (mbar) to Inches of Mercury (inHg) is a common pressure conversion. 1 mbar equals 0.02953 inHg. For example, 100 mbar is equal to 2.952998 inHg.
Quick Reference Values
1 mbar = 0.02953 inHg. 5 mbar = 0.14765 inHg. 10 mbar = 0.2953 inHg. 25 mbar = 0.73825 inHg. 50 mbar = 1.476499 inHg. 100 mbar = 2.952998 inHg.
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 Inches of Mercury?
Inches of Mercury (inHg) is a unit of pressure. Inches of mercury measure pressure as the height of a mercury column in inches exerted by atmospheric or other pressures. One inch of mercury equals exactly 3,386.389 pascals (Pa). This unit is commonly used in barometry and aviation altimetry [nist-si-guide]. The unit originates from mercury barometers developed by Evangelista Torricelli in 1643. Measuring pressure via mercury column height became standard in meteorology and aviation. The inch unit was adapted for use in English-speaking countries [nist-si-guide]. Inches of mercury are used mainly in the United States and Canada for weather reports and aircraft altimeters. Internationally, the pascal is preferred, but inHg remains common in aviation and HVAC industries [nist-si-guide].
Common Misspellings
People often search for this conversion using these alternate spellings: milibars, milibars, millibar, milibar, inch of mercury, inch-mercury, in hg, inches mercury. All of these refer to the Millibars to Inches of Mercury conversion.
