Question

unit less quantities are dimensional less​

Answer 1

Since both quantities have the dimension length, their ratio is dimensionless. ... It has been argued that quantities defined as ratios Q = A/B having equal dimensions in numerator and denominator are actually only unitless quantities and still have physical dimension defined as dim Q = dim A × dim B−1.
