Do you always convert to SI units for calculations?
Like for empirical formula you use grams, not Kg. Then what is the point of SI units?

I think it's important to keep in mind what you are solving for. For example, if you are solving for E, the units for E are Joules, which translates to kg*m2*s2.
Therefore, it's helpful convert your constants and variables to match units of kg and m so that you don't get confused or end up with the wrong answer.

Yes, I agree. SI units are a great way of checking whether or not your are on the right track. If the units, when cancelled out, leave you with the desired units, you can assume that your answer is right (given the math is done correctly).

As long as the units are the same on each side, it doesn't really matter because you can always convert btwn the different ^10 levels. The only trouble is for units like Joules where its specifically kg, and as long as you know that (or the entirety of the joules unit breakdown), you're fine.
