# Give the MKS units for the following quantities.Power of lens.

Dioptre.

##### SOLUTION
The dioptre is the unit of measure for the refractive power of a lens. The power of a lens is defined as the reciprocal of its focal length in meters, or $D = \dfrac 1f$, where $D$ is the power in diopters and $f$ is the focal length in meters.
