HERE IS THE ANSWER FOR YOUR QUESTION;

◆ A unit need not always mean a physical unit. So a dimensionless quantity will always be independent of the base units — meter, second, kilograms, kelvin, candela, moles, ampere. But there are other quantitiesthat are dimensionless, but have a unit. For example, radian is the unit for an angle.
