Thermometer, thėr-mom′e-tėr, n. an instrument for measuring the variations of sensible heat or temperature.—adjs. Thermomet′ric, -al, pertaining to, or made with, a thermometer.—adv. Thermomet′rically.—For the Centigrade and the Fahrenheit scale and their relations to each other, see Centigrade and Fahrenheit. In the Réaumur scale, still largely used in Russia and Germany, the freezing-point is marked zero, and the space between this and boiling-point is divided into 80 degrees. To reduce it to Fahrenheit, multiply by 2¼ and add 32; to Centigrade, increase the number by one-fourth of itself. Thus: F = 9⁄5 C + 32 = 9⁄4 R + 32; C = 5⁄9 (F - 32) = 5⁄4 R; R = 4⁄9 (F - 32) = 4⁄5 C.—Maximum thermometer, one that registers the maximum temperature to which it is exposed; Minimum thermometer, one that registers the minimum temperature to which it is exposed. [Gr. thermē, heat, metron, a measure.]
