Celsius Scale

Celsius Scale. A temperature scale, named after the Swedish astronomer Anders Celsius who devised it, that is based on 0¦ for the freezing point of water and 100¦ for its boiling point (q.v.) at sea level or under one atmosphere of air pressure. It is also called the Centigrade scale because the intervals between the two base points are calibrated into 100 equal degrees. It is in general use in those countries where the metric system (q.v.) has been adopted, as well as in scientific work everywhere. Temperatures on the Fahrenheit (¦F) scale (q.v.) can be converted to the Celsius (¦C) scale by the following formula: ¦C = 5/9(¦F - 32).
