If I was trying to find the velocity of something in cm, could I use 9.8m/s^2 or would I have to convert that acceleration into cm?

yes, u need to convert it to cm/s^2
9.8m/ss = 980cm/ss

Firstly, the velocity of something is expressed either in cm/s or m/s. All our motion formulas ask for velocity in m/s. So, go ahead and use the formulas, but once you get the velocity in m/s then multiply it by 100 to convert it to cm/s.
Secondly, to be consistent in your units while using the motion formulas, adopt 9.8m/s^2. Your work will be simpler that way. As I said above, it's only after you have arrived at the value of the velocity will you then convert to the cm/s unit.

you could use that, but then ud have to multiply that answer by 100 to get it into cm
