In international units, the mass of an object is measured in kilograms. Smaller objects may be expressed in grams, in milligrams, micrograms, etc.
microscopes are used to measure the length of microscopic objects Microscopic objects are those which cannot be seen by naked eyes..Unit used to measured is micrometer.1000000 micrometer=1 m.
The SI unit is meter. But nanometer and angstrom are commonly used units to measure the wavelength of light.
The lumen is the unit used to measure the rate at which light energy is radiated from a source. The lumen represents the international standard unit of luminous flux that is based on the candela.
The index of refraction is a unitless ratio. It has no units, it is a pure number.

it is light years. And miles are to short.
Not sure what you mean with "light build". The SI (metric) unit for mass is the kilogram. For small objects, smaller units such as grams and milligrams can be used; for larger objects, the ton (= 1000 kilograms) is also used.
The Astronomical unit is used to measure the large distances in our solar system. It is roughly the average distance between the Earth and the Sun.
light years
That's a unit of density.
The volumes of all objects are expressed in the third power of whatever units are being used to measure their dimensions. For example, if an object is very small and you measure its dimensions in millimeters, its volume would be expressed in cubic millimeters.
microscopes are used to measure the length of microscopic objects Microscopic objects are those which cannot be seen by naked eyes..Unit used to measured is micrometer.1000000 micrometer=1 m.
Sunlight is light.The word has been added as the light comes from the sun.Light is measure in candela as a unit ofmeasurement.A Lux meter is used to measure light in the unit of candela.
The SI unit is meter. But nanometer and angstrom are commonly used units to measure the wavelength of light.
The official, SI unit of mass is the kilogram.
Light years (the distance that light travels in one year) and parsecs, which is approximately equal to 3.26 light years. For very distant objects, the units of "mega-parsecs" (millions of parsecs) are sometimes used, sometimes abbreviated as "Mpc".
