Atmospheres to Torr Conversion
Converting Atmospheres (atm) to Torr (Torr) is a common pressure conversion. 1 atm equals 760.0021 Torr. For example, 100 atm is equal to 76,000.210018 Torr.
Quick Reference Values
1 atm = 760.0021 Torr. 5 atm = 3,800.010501 Torr. 10 atm = 7,600.021002 Torr. 25 atm = 19,000.052504 Torr. 50 atm = 38,000.105009 Torr. 100 atm = 76,000.210018 Torr.
What is Atmospheres?
Atmospheres (atm) is a unit of pressure. One atmosphere (atm) is a unit of pressure defined as exactly 101,325 pascals (Pa). It approximates the average air pressure at sea level on Earth. The atmosphere unit is used for expressing pressures in meteorology and engineering [iso-80000]. The atmosphere was originally defined in the 19th century based on average sea-level air pressure. It was standardized by the International Union of Pure and Applied Chemistry (IUPAC) and other bodies to equal 101,325 Pa in the mid-20th century [nist-sp-811]. Atmospheres are used worldwide in scientific fields, including chemistry and physics, and in engineering applications like pressure vessel design. It is less common in everyday use outside these fields [nist-sp-811].
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].
Common Misspellings
People often search for this conversion using these alternate spellings: atmosphers, atmosfere, atmospere, atmospherics, tor, torrs, torr pressure. All of these refer to the Atmospheres to Torr conversion.
