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).

n: (SI) a system of units of measurement based on the metric system, adopted and described by the Eleventh General Conference on Weights and Measures. It provides an international standard of measurement to be followed when certain customary units, both US and metric, are eventually phased out of international trade operations. The symbol SI (Le Syste`me International dUnites) designates the system, which involves seven base units: (1) metre for length, (2) kilogram for mass, (3) second for time, (4) Celsius for temperature, (5) ampere for electric current, (6) candela for luminous intensity, and (7) mole for amount of substance. From these units, others are derived without introducing numerical factors.
