How anders celcius defined temperature scale.

  1. Dec 17, 2016 #1
    What made anders celcius(founder of °c temperature scale) to use water as a bench mark for measuring temperature, why he used water's freezing point as 0°c and boiling point as 100°c, is there a reason or he just used water so that it can work easily.

    Celsius actually defined it the other way round, with zero as boiling and 100 as freezing! It was changed round later by Linnaeus and others.

    Water was easy to work with, although the fact that the boiling point varied significantly with pressure was a bit of a problem.

    For more detail see the Wikipedia article on Celsius.
