there are 3 units because it is easier to use some when dealing with certain temperature scales. On a day to day basis, it is easier to use celsius or farenheit because we are not dealing with large numbers or very positive/negative temperatures for which kelvin might be more suitable.
In today's lecture we learned that Celsius is often used for measurements, and Kelvin is often used in calculation. One of the reasons is probably that Celsius and Kelvin have the same size of scale (K=C+273.15), making it easier to convert one of them to the other. :)
the three temp scales (F,C,K) vary because their scale makes different types of thermal measurement easier. For example, while F can show more minute changes in temp per degree, the scale of C is based off the boiling and freezing points of water (so it is better for math involving solutions in chemistry), and the K scale is more extreme (k=0 is absolute zero) so it is better for experiments involving extreme temperatures
The most common form of measurement is Celsius, Kelvin is almost used in relation with celsius as it is an absolute scale meaning that it indicates the temperature at which molecules stop moving (0K = absolute zero).
