Explanation:
No, it is not true to say that a quantity have dimensions but still have no units. The reason behind this is that dimensions are derived from the units. But its inverse can be true i.e. a quantity have no dimension but it have units. For example angle have unit (radian/degree) but it is a dimensionless quantity.
