Creating a new temperature scale using Celsius as a reference-Physics

If a non-human civilization were to develop on Saturn's largest moon, Titan, its scientists might well develop a temperature scale based on the properties of methane, which is much more abundant on the surface than water. Methane freezes at -182.6°C on Titan, and boils at -155.2°C. Taking the boiling point of methane as 100.0°M (degrees Methane) and its freezing point as 0°M, what temperature on the Methane scale corresponds to the absolute zero point of the Kelvin scale?

-155.2+182.6 = 27.4 so each degree M is 0.274C

0.0K is -273.15C (see link) so (-273.15+182.6)/0.274 is temperature in M.


only one decimal place in your answer
