The SI unit of power of a lens is the diopter, which is represented by the symbol D. It is defined as the reciprocal of the focal length of the lens measured in meters.
diopter
I don't know about SL. If you mean SI, the unit of power is the watt (equal to joules/second).
The unit of power of a lens in the MKS system is diopters (D), which is defined as the reciprocal of the focal length of the lens in meters.
The unit of measurement of a lens's refractive power is diopters. It is denoted by the symbol "D" and is used to measure the ability of a lens to converge or diverge light.
The unit of measurement for lens refractive power is diopters (D), which indicates the strength of the lens to bend light. Positive values indicate converging power (for correcting farsightedness), while negative values indicate diverging power (for correcting nearsightedness).
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).
The SI unit for power is the watt, symbolized as W.
The SI unit of power is the watt, defined as joules/second. Joule is the unit for energy.

the answer for the si unit of power is the watt or w
That is called "power". The SI unit of energy is the joule, the SI unit for power is the watt, which is equal to joules/second.That is called "power".

No one. A horse power is an Imperial measurement unit, not an SI unit and so a metre would not have featured!No one.

Please don't write "these", implying a list, which you don't provide.The SI unit of power is the watt = joules/second. The SI unit of energy is the joule.
