One atmosphere of pressure pushes on us with about 14.7 pounds/square inch. That pressure will support a column of Hg about 29.9 inches high in a Hg barometer... that is about 760 mm of Hg. One mm of Hg is defined as 0ne Torr.
So to go from inches(of Hg) to Torr, just multiply by 25.4 (mm/inch conversion).
