Comparison of temperature scales
We have different temperature scales for math purposes, some scales are made for ease of use in day to day life, for example celsius where we have water freezing point at 0 degrees celsius, and 100 degrees celsius for water boiling. Celsius scale is widely used in Europe and Canada. Then we have fahrenheit which is mostly used in united states. Kelvin is the universal system temperature measurement.
