The torr is a unit of pressure based on an absolute scale, now defined as 1/760 of a standard atmosphere. Thus one torr is 101325/760 pascals. One torr was intended to be the same as one "millimeter of mercury". However, subsequent redefinitions of the two units made them different; the torr is not part of the International System of Units, but it is combined with the metric prefix milli to name one millitorr or 0.001 Torr. The unit was named after Evangelista Torricelli, an Italian physicist and mathematician who discovered the principle of the barometer in 1644; the unit name torr is written in lower case, while its symbol is always written with upper-case initial. The symbol should be used with prefix symbols; the torr is sometimes incorrectly denoted by the symbol "T", the SI symbol for the tesla, the unit measuring the strength of a magnetic field. Although encountered, the alternative spelling "Tor" is incorrect. Torricelli attracted considerable attention when he demonstrated the first mercury barometer to the general public.

He is credited with giving the first modern explanation of atmospheric pressure. Scientists at the time were familiar with small fluctuations in height; when these fluctuations were explained as a manifestation of changes in atmospheric pressure, the science of meteorology was born. Over time, 760 millimeters of mercury at 0 °C came to be regarded as the standard atmospheric pressure. In honour of Torricelli, the torr was defined as a unit of pressure equal to one millimeter of mercury at 0 °C. However, since the acceleration due to gravity—and thus the weight of a column of mercury—is a function of elevation and latitude, this definition is imprecise and varies by location. In 1954, the definition of the atmosphere was revised by the 10e Conférence Générale des Poids et Mesures to the accepted definition: one atmosphere is equal to 101325 pascals; the torr was redefined as 1/760 of one atmosphere. This yields a precise definition, unambiguous and independent of measurements of the density of mercury or the acceleration due to gravity on Earth.

Manometric units are units such as millimeters of mercury or centimeters of water that depend on an assumed density of a fluid and an assumed acceleration due to gravity. The use of these units is discouraged. Manometric units are used in medicine and physiology, they continue to be used in areas as diverse as weather reporting and scuba diving; the millimeter of mercury by definition is 133.322387415 Pa, approximated with known accuracies of density of mercury and standard gravity. The torr is defined as 1/760 of one standard atmosphere, while the atmosphere is defined as 101325 pascals. Therefore, 1 Torr is equal to 101325/760 Pa; the decimal form of this fraction is an infinitely long. The relationship between the torr and the millimeter of mercury is: 1 Torr = 0.999999857533699... mmHg 1 mmHg = 1.000000142466321... TorrThe difference between one millimeter of mercury and one torr, as well as between one atmosphere and 760 mmHg, is less than one part in seven million; this small difference is negligible for most applications outside metrology.

Other units of pressure include: The bar, defined as 100 kPa exactly. The atmosphere, defined as 101.325 kPa exactly. The torr, defined as 1/760 atm exactly; these four pressure units are used in different settings. For example, the bar is used in meteorology to report atmospheric pressures; the torr is used in high-vacuum engineering. NPL – pressure units

William Edward Buckley was a Church of England clergyman, an academic who taught both classical languages and Old English, a journalist. He was Rawlinsonian Professor of Anglo-Saxon at the University of Oxford from 1844 to 1849. Buckley was the fourth son of Joseph Buckley, of the Crescent, of Ordsall Hill, by his marriage to Jean, a daughter of Frazer Smith of Stromness and was the grandson of John Buckley, he was one of eight children, who all survived to adulthood and were still living in 1874. In 1817 Joseph Buckley was boroughreeve, in 1825 he moved his family to Devon. Another of his sons, Joseph Buckley went into the church and became Rector of Sopworth, Wiltshire. Buckley was educated at Tiverton Grammar School, Exeter School, Brasenose College, where he was admitted on 10 June 1835. In 1839 he graduated BA and in the Michaelmas term of the same year was President of the Oxford Union. In 1842 his degree was promoted to MA. In 1842 Buckley became a Fellow of Brasenose College and from 1844 to 1849 was Rawlinsonian Professor of Anglo-Saxon, succeeding Henry Bristow Wilson.

In 1853 he became a rural dean. He was Professor of Classics at Haileybury College until it was closed by the East India Company in January 1858. For some years he was on the staff of The Times newspaper and was a contributor to Notes and Queries, he edited some of the publications of the Roxburghe Club and in 1884 was elected as its vice-president. He died at Middleton Cheney on 18 March 1892. One obituary said of him "A man of many friends, he was an excellent talker, full of geniality and good stories", his books were sold in two sales at Sotheby's, in February 1893 and April 1894, for a total of £9,420.

Simone Favaro is an Italian international rugby union player. He made his debut for Italy against Australia on 20 June 2009, he played for Glasgow Warriors and Treviso in the Pro12. Favaro plays at flanker. Favaro, the son of former Italy lock Roberto Favaro, started playing rugby aged nine while living in Zero Branco, on the advice of a family friend. After playing for the Treviso under-19 team he played in the Super 10 with Rovigo and Overmach Parma, he began his professional career playing for the Treviso under-19 team. In June 2010 he joined Aironi for their first season in the Celtic League, he moved back to Treviso. On 18 February 2015 it was announced that Favaro would sign for the Scottish side Glasgow Warriors for the 2015–16 season in the summer of 2015. Favaro signed until May 2017, he became a fans favourite and won Player of the Season in his first year with the club. On 20 February 2017 it was announced, it was announced that Favaro would sign for Stade Français for the 2017-18 season, however Favaro instead signed for Fiamme Oro in Italy's National Championship of Excellence.

Favaro was an early developer and, at the age of 20, was the youngest player included in Nick Mallett's squad for the 2009 Six Nations Championship. Favaro did not feature in the Championship.
