SI Unit Kg

Postby Vista_Farkhondeh_3O » Tue Sep 27, 2016 11:48 pm

If the SI unit for mass is kg, is it preferable to leave answers in kg or just g?

In most chemistry problems I've encountered in my high school chemistry courses, most answers were in grams. It might be easier to report answers in grams especially when a problem requires using dimensional analysis using the molar mass from the periodic table which is given in grams/mole.

It's conventional to report your answer in the units given to you by the question, unless it asks explicitly for you to provide an answer in a specific unit. I think the need to remain in Kg is stressed more in physics, however.

As far as I've seen, in chemistry it is more common to put your answer in grams while in physics it is more common to put your answer in kilograms. In chemistry, however, unless the problem states otherwise, you should be able to put your answer in both kilograms or grams, whichever way your prefer, as long as you have the significant figures correct.
