Figure shows Farhenheit, Celsius and Kelvin scales. In that order, the scales have these values: absolute zero is minus 459, minus 273.15 and 0, freezing point of water is 32, 0 and 273.15, normal body temperature is 98.6, 37 and 310.15, boiling point of water is 212, 100 and 373.15. Zero degree F is minus 17.8 degree C and 255.25 degree K. The relative sizes of the scales are shown on the right. A difference of 9 degrees F is equivalent to 5 degrees C and 5 degrees K.
