n: the metric scale of temperature measurement used universally by scientists. On this scale, O represents the freezing point of water and 100. its boiling point at a barometric pressure of 760 mm. Degrees Celsius are converted to degrees Fahrenheit by using the following equation: ﾰF = 9/5 (ﾰC) + 32. The Celsius scale was formerly called the centigrade scale;now, however, the term Celsius" is preferred in the International System of Units (SI).
