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.
