1 light year is the distance traveled by the light in 1 year through vacuum.
So, 1 light year = distance traveled by the light in 1 year
But, distance traveled = speed of light × time taken
= 3 × 10 raised to the power 8 × 1 year
But 1 year = 365 days = 365 × 24 hours = 365 × 24 × 60 minutes = 365 × 24 × 60 × 60 seconds
So, 1 light year = 3 × 10 raised to the power 8 × 365 × 24 × 60 × 60
i.e. 1 light year = 9.46 × 10 raised to the power 12 kilometer or 9.46 × 10 raised to the power 15 meter [Approximate value]
