Diopter (D)...
diopter
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).
The symbol for the unit of measurement of power is "W" for watt.
I assume "molecular refractive index" refers to "the refractive index of a group of molecules". In this case, you just use the units for a refractive index - i.e., a dimensionless number.
Watts. -- The base units for power are Kg*m^2/s^2.Power is the rate at which work is done or energy is transmitted.The units of power are the units of energy divided by time.The SI unit of power is the watt (W), which is equal to one joule per second.The older Imperial unit was horsepower (1 HP equal to about 745.7 watts).

The unit of measurement that represents true power is the watt (W).
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).

Horsepower is abbreviated to hp. It is a unit of measurement that represents the power of an engine.
10 to the twenty-third power is not a unit of measurement. It is a number.
The 3rd power (cube) of any length unit is a unit of volume.

The basic metric unit for electrical power measurement is the watt, which is equal to one joule per second.
