    Hi,
    Just a question on percentage error. I know the formula and how to use it, but wondering if both numbers in the formula have to have the same units.
    For example, a 25cm3 pipette has an error of +/- 0.06ml.
    Is it okay to just do (0.06/25) x 100, or do I need to conver the 0.06ml into cm3?
    Thanks

    Must be the same units. Are you sure the 0.06 isn't already in cm3?

    0.06ml seems way too small. Maybe pipettes are that accurate though?! :p:
