Question

$1	ext{ m}$ is equivalent to approximately how many light years (ly)?

Professor PC Thomas Classes · Answer

One light year is the distance light travels in one year: $1	ext{ ly} = 9.46 	imes 10^{15}	ext{ m}$. Therefore, $1	ext{ m} = \frac{1}{9.46 	imes 10^{15}}	ext{ ly} \approx 1.057 	imes 10^{-16}	ext{ ly}$.
