What is dielectric constant formula?

The dielectric constant (k) of a material is the ratio of its permittivity ε to the permittivity of vacuum ε o , so k = ε / ε o. The dielectric constant is therefore also known as the relative permittivity of the material. Since the dielectric constant is just a ratio of two similar quantities, it is dimensionless.

What is the unit of dielectric constant?

The dielectric constant is the ratio of the permittivity of a substance to the permittivity of free space.it's unit f/m. 3.9.
