temperature scales Celsius and Centigrade?

In practical terms there is no difference. One degree Celsius is the same as one degree Centigrade.

However there are clues in the word Centigrade alluding to its origins and common usage. Cent, meaning one hundred and grade meaning scale tells that Centigrade is that part, from zero degrees, anders_celsius.jpg the freezing point of pure water to 100 degrees, water’s boiling point, of the overall Celsius scale, which was named after Swedish physicist Anders Celsius 1701-1744. Whereas the Celsius scale starts at minus 273.15, which is 0 Kelvin and scientifically therefore Absolute Zero. Meaning there can be no lower temperature, and for all we
know at the other end, infinity.

Centigrade is aligned, linguistically at least, most closely with that part of the temperature scale associated with the human experience. For example:- Minus 70 degrees Centigrade being considered very cold and un-survivable and similarly 55 degrees Centigrade being hot for breathable air and time to seek shade if you wish to survive. 100 degrees Centigrade being necessary for boiling water if you want a decent cup of tea whilst doing it.
