The Q of an inductor with a series loss resistance is the Q of a resonant circuitusing that inductor (including its seriesloss) and a perfect capacitor. ... ω0 is the resonance frequency in radians per second, L is the inductance, XL is the inductive reactance, and. RL is the series resistance of the inductor.

Hey !!
The quality factor (Q) of series LCR circuit is defined as the ratio of the resonant frequency to frequency band width of the resonant curve.
Q = ωr / ω₂ - ω₁ = ωrL / R
Therefore, clearly smaller the value of R, larger is the quality factor and sharper the resonance. Thus, quality factor determines the nature of sharpness of resonance.
It has no Units.
Good luck !!
