Torr to Millibars Conversion
Converting Torr (Torr) to Millibars (mbar) is a common pressure conversion. 1 Torr equals 1.33322 mbar. For example, 100 Torr is equal to 133.322 mbar.
Quick Reference Values
1 Torr = 1.33322 mbar. 5 Torr = 6.6661 mbar. 10 Torr = 13.3322 mbar. 25 Torr = 33.3305 mbar. 50 Torr = 66.661 mbar. 100 Torr = 133.322 mbar.
What is Torr?
Torr (Torr) is a unit of pressure. The torr is a unit of pressure equal to exactly 1/760 of an atmosphere or 133.322 pascals (Pa). It approximates the pressure exerted by a 1-millimeter column of mercury at 0°C. The torr is widely used in vacuum physics and engineering for pressure measurements [nist-si-guide]. Named after Evangelista Torricelli, who invented the mercury barometer in 1643, the torr was formalized to provide a practical pressure unit close to the millimeter of mercury but with precise SI equivalence. It was standardized by scientific bodies in the 20th century [nist-si-guide]. The torr is used globally in laboratories and industries requiring vacuum measurements, such as semiconductor manufacturing. It is recognized by ISO and NIST as a pressure measurement unit alongside the pascal [nist-si-guide].
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].
Common Misspellings
People often search for this conversion using these alternate spellings: tor, torrs, torr pressure, milibars, milibars, millibar, milibar. All of these refer to the Torr to Millibars conversion.
