Converting from Light Year (ly) to Megaparsec (Mpc) | Astronomy distance

What is Light Year (ly)

A Light Year (ly) is a unit of astronomical distance. It represents the distance that light travels in one year in a vacuum. Light travels at a speed of approximately 186,282 miles per second (299,792 kilometers per second), which means one light year is equivalent to about 5.88 trillion miles (9.46 trillion kilometers).

What is Megaparsec (Mpc)

A Megaparsec (Mpc) is another unit of astronomical distance commonly used in cosmology. It is equal to one million parsecs, with a parsec being approximately 3.26 light years. Therefore, a Megaparsec is roughly 3.26 million light years.

Conversion Formulas

When converting from Light Years to Megaparsecs, you can use the following formula:

Mpc=ly×0.0000003066014

And when converting from Megaparsecs to Light Years, the formula is:

ly=Mpc×3261564

Examples

1. Converting 4 Light Years (ly) to Megaparsecs (Mpc):

Mpc=4×0.0000003066014=0.000001226406

2. Converting 16 Light Years (ly) to Megaparsecs (Mpc):

Mpc=16×0.0000003066014=0.000004905622

3. Converting 6 Megaparsecs (Mpc) to Light Years (ly):

ly=6×3261564=19569380

These conversions allow astronomers to easily navigate between the vast distances in our universe.
