WebThe polymath Isaac Newton (1643-1724) used linseed oil in his sealed-in-glass thermometers. His scale used three fixed-points: the temperature of air when water begins to freeze, the heat of blood in the human body and rapidly boiling water. On Newton's scale, freezing air was 0º, blood heat was 12º and boiling water was 34º. http://boson.physics.sc.edu/~rjones/phys101/Fahrenheit how many sq ft is 16x20
