|+||A scale of temperature measurement used primarily in areas other than the United States; in the US, the Fahrenheit scale is most often used. For many years it was called Centigrade but was adopted as the standard term in 1948. It was in 1742 the Swedish astronomer Andres Celsius published a paper in the "Kungliga Swenska Wetenskaps Academiens Handlingar" (easy for YOU to say...it wasn't even easy for me to type), the Annals of the Royal Swedish Academy of Science, entitled "Observations on two persistent degrees on a thermometer". This paper is the origin of the Celsius temperature scale. In today's computer industry, all electrical components have a range of temperature within which they operate. The Celsius scale ranges from 0 to 100 degrees. As a quick reference without getting too technical, 0 is freezing and 100 is boiling. Most measurements worldwide and in the computer industry are in Celsius, except in the chip manufacturing process where Kelvin is used.|
