→ Light year is the unit of length (Light year is a unit of distance).

→ Light year is a unit of measurement of distance travelled by light in vacuum in one year.

→ A light year is used to measure the vast distances between celestial objects like stars and galaxies.

→ 1 light year = 9.46 × 1015 m

→ An astronomical unit (AU) is used to measure the distance between celestial bodies, within a solar system, such as the distance from the Sun to other planets.

→ One astronomical unit is the average distance between the Earth and the Sun.

→ An astronomical unit is defined as the average distance between the center of the Earth and the center of the Sun.

→ 1 astronomical unit (AU) = 1.496 × 1011 m = 149.6 million km.

→ Parsec is a unit of length.

→ Parsec is used for measuring large distances to objects outside the solar system, such as stars and galaxies.

→ 1 Parsec = 3.26 light year

→ 1 Parsec = 3.08 × 1016 m

→ Parsec > light year > astronomical unit.

→ Parsec is the largest unit to measure distance.

→ 1 nautical mile or seamile = 6076.12 feet

→ 1 nautical mile or seamile = 1.852 km

→ 1 micron (μm) = 10−6 m
