torr

a unit of pressure equal to one millimetre of mercury (133.322 newtons per square metre)

Torr

 

a subsidiary unit of pressure equal to 1/760 of an atmosphere. More precisely, a torr is equal to 101,325 newtons per m2 ÷ 760 = 133.322 newtons per m2, or 133.322 pascals. The torr was named in honor of E. Torricelli; the international symbol is Torr. An equivalent unit, the millimeter of mercury (mm Hg), is used more often in Russian scientific literature.

torr

[tȯr]
(mechanics)
A unit of pressure, equal to 1/760 atmosphere; it differs from 1 millimeter of mercury by less than one part in seven million; approximately equal to 133.3224 pascals.
