Unit, cubic foot. Weight: (W) Unit, pound, which is 7000 grains avoirdupois, or 453.6 grams. Temperature CONVERSION EQUATIONS Fahrenheit degrees = 9/5 centigrade degrees + 32. Centigrade degrees = 5/9 (Fahrenheit degrees -- 32). Absolute temperature, expressed in Fahrenheit degrees = Fahrenheit degrees + 459.6. In heating and ventilating work, 460 is usually used. Absolute temperature, expressed in centigrade degrees = centigrade degrees + 273.1.
