I learned this in fluid dynamics class for learning about non dimensional value that are used like Reynolds numbers, but more broadly it was a bit like a cheat code because often we had an exam question with units of inputs and then the final answer in another set of units, and even without knowing the correct equation you could with a little intuition, derive the correct solution by combining the input units in fun ways, Understanding the MLT system in this way made most of mechanical engineering much more straightforward, and I used this almost every day up to my masters degree in computational fluid dynamics.
