What is the SI unit of converging ability of a lens?

Optical power (also referred to as dioptric power, refractive power, focusing power, or convergence power) is the degree to which a lens, mirror, or other optical system converges or diverges light. It is equal to the reciprocal of the focal length of the device.[1] The dioptre is the most common unit of measurement of optical power. The SI unit for optical power is the inverse metre (m−1).
