TORR (TORR; MM HG)

Compare with barometer and pressure .A unit of pressure , defined so that 760 Torr is exactly 1 atmosphere . A Torr is equivalent to 1 mm Hg on barometer readings taken at 0°C; at other temperatures, the conversion from mm Hg to Torr is approximately p(Torr) = p(mm Hg) × (1 - 1.8×10 -4 t), where t is in °C.
