As a very young mathematician, you may have “gotten into the habit” of just doing math with numbers when you needed to convert from one unit to another.
Someone asks you “how many eggs in three dozen eggs”? You think for a second and “3×12” in your head and then answer, “36 eggs”.
Sure, you can get away with doing this for simple problems, but as you work your way deeper into the dark jungles of science, the difficulty of the problems is going to increase…
