Unit Notation

Postby LorenzoDuvergne3I » Wed Oct 03, 2018 11:08 pm

Is there any particular reason why in the textbook most units that are one unit over another (Eg molar mass being grams/mol) are written using exponents (Using the same example molar mass being grams*mol^-1)? It seems unnecessary and I'm wondering if there is a reason why the / sign is avoided or why exponents are preferred.

It just makes it simpler to look at. The negative exponent and division sign mean the same thing but all of the /'s get confusing, so I prefer using the negative exponent method. It also helps with dimensional analysis bc the units are clearer.

I am guessing that the textbook uses the -1 exponent, because it might be confused as an 'or' sign on print. But at the end of the day, it is the same thing.
