Unit less quantities are dimensional less

1.	Unit less quantities are dimensional less
Answer» oth 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.
