A measurement of the hotness or coldness of an object or of the environment. The International Standard (SI) units for temperature are degrees Celsius. The Celsius scale is set as a linear function of the thermometric properties of pure water. The freezing point of Water at 1 atm (sea level) is designated 0C while the boiling point of water is designated as 100 C. The one hundred degree differential gave the scale its first name of centigrade. The Celsius scale related to the archaic Fahrenheit scale by the equation: T (C) = 0.555 [T (F) -32 ] .
