You cannot 'measure' light. However, there is the light-year, a measurement of the distance light can travel in one year.
there are many. Lumens, cadlepower, foot candles and candelas. There are probably a few more.
The unit of metric measurement most useful for light microscopy is the micrometer (μm), which is one-thousandth of a millimeter. This unit allows for precise measurements of objects that can be visualized under a light microscope.
"light-year"
The distance light travels in one year is called a light-year. To get the number 9,470,000,000,000, the unit used is the kilometer.
In optical density measurements, D typically stands for "Absorbance" and is commonly used as a unit of measurement to quantify the amount of light absorbed by a sample. The higher the D value, the more light is absorbed by the sample.
An astronomical unit (AU) is a unit of measurement used in astronomy that is equal to the average distance between the Earth and the Sun, about 93 million miles. A parsec is a unit of measurement used to describe astronomical distances, equal to about 3.26 light-years or 206,265 AU.
The unit of measurement is the "light year".
A candela is a unit of measurement for light sources and light emissions. Light beams projects different color at different wavelengths, and a candela is used to measure the intensity of the light.

Light Year is unit for all astronomic distances
The unit of measurement used to measure distances between galaxies is typically the light-year, which is the distance that light travels in one year. This unit is used because of the vast distances involved in intergalactic space.
