Webb0.019 336 77 psi. The torr (symbol: Torr) is a unit of pressure based on an absolute scale, defined as exactly 1 760 of a standard atmosphere ( 101 325 Pa ). Thus one torr is exactly 101 325 760 pascals (≈ 133.32 Pa). Historically, one torr was intended to be the same as one "millimeter of mercury", but subsequent redefinitions of the two ...
