    Answer:

    A dimension is a measure of a physical variable.

    Unit is a way to assign a number or measurement to that dimension.

    In dimensional analysis, a dimensionless quantity is a quantity to which no physical dimension is assigned, also known as a bare, pure, or scalar quantity or a quantity of dimension one, with a corresponding unit of measurement is the SI of the unit one, which is not explicity shown.
