Including Units in a Problem

[Minu Reddy]

I have a question regarding including si units when we are solving a problem on any form of assessment?
Is it necessary to include units at all times or only in the final answer?

Thnak you very much.

I think it is always a good idea to show units throughout the problem just for you to know what the unit of measurement is/ keep track what you need in the final answer. It's always better to be safe and just use them throughout the problem. In regards to if its required, I'm not entirely sure.

I'd say that units are required in any scientific problem, especially if they are included. Also, keeping track of units throughout the process of solving a problems makes it easier to see where and why units cancel.

You will have to include units if you're doing dimensional analysis, which is a great way to make sure that you are using the right values in your calculations and to finish with the correct type of units. Here's a link to the Khan Academy explanation of dimensional analysis:
