Cell constant $=\frac{\mathrm{\ell }}{\mathrm{A}}={\mathrm{m}}^{-1}$ 

Conductivity $\mathrm{k}=\frac{1}{\mathrm{\rho }}=\frac{\mathrm{\ell }}{\mathrm{RA}}={\mathrm{\Omega }}^{-1}{ \mathrm{m}}^{-1}$ 

Molar Conductivity $={\mathrm{\lambda }}_{\mathrm{m}}=\frac{\mathrm{k}\times 1000}{\text{ Molarity }}=\mathrm{S} {\mathrm{cm}}^2 {\mathrm{mol}}^{-1}$

Degree of dissociation $=$ Number of mole dissociated out of one mole, hence, it is dimensionless.
