The unit used to measure the energy of an electromagnetic wave is called a photon.
. . they are a convenient unit. Another convenient unit is the parsec.
there is a device called a hydrometer that measures humidity. theres a unit to measure heat called a calorie. those are two to measure it!
If I remember all of my astronomy classes correctly, the unit of measurement between Earth and the Sun is 1 A.U., or Astronomical Unit, which is equal to 93 million miles. 1 light year is equal to 5,865,696,000,000 miles (9,460,800,000,000 km). Astronimical Units are used to measure distance within our own galaxy. To measure the distance between stars and galaxies, the unit is called a parsec (PC). 1 PC = 3.26 light years. Hope this helps!

SI unit kilogram is used to measure mass. It is abbreviated as kg.
It's called volume I think.
A stellar unit refers to a unit of distance used in astronomy to measure the distance between stars. It is typically equivalent to the mean distance between stars within a galaxy, which can vary depending on the galaxy being observed.
