Light years are a unit of distance used to measure vast distances in space. To measure light years, scientists use tools like telescopes and spectrographs to observe the light emitted by stars and galaxies. By analyzing the light's properties, such as its brightness and spectrum, scientists can calculate the distance to these celestial objects in terms of light years.
Scientists use a ruler to measure the length or size of objects in their experiments or studies. Rulers provide a standardized unit of measurement, allowing scientists to collect and compare data accurately.

Scientists use a unit called atomic mass unit (amu) to measure the mass of particles within an atom. This unit is based on the mass of a proton or neutron, and it helps scientists compare the mass of different atoms accurately.
Scientists use celsius and kelvin. The SI unit for temperature is Celsius.
Kelvin (K)
The SI unit for mass is the kilogram (kg)
SI unit system is used by all scientists.. Hence, it is a standard unit for measurement.
That's a unit of density.
