Who is the first person to invented Centigrade temperature scale?
Anders Celsius proposed this scale in 1742, defining 100 degrees as the freezing point of water and 0 degrees as the boiling point. This was reversed before his scale was actually put to use. The 100 degree difference led to the ‘cent’ prefix, indicating each division was 1/100 of the difference. Since ‘centigrade’ is a geometric measurement of angles in Spanish-speaking countries, it was sometimes called the Celsius scale but it was not until 1948 that this name was officially adopted by the scientific community.
