It helps you to answer questions easier than you expected,If you are confused about the answer to a question,you can simply use the dimensional formula to get to the answer.Bit it can't always be applied if two or more options having same dimensions are given. For eg:You are asked to find the work done in a giben situation.But you are unable to get to the answer due to some errors in intervening steps.In such cases,you can apply dimensional formula to arrive at the answer and equate the formula to the dimensions of work, if and only if all the options have different dimensions.
