How to convert light years to micrometers
One light year equals 9.46073 × 10²¹ micrometers, so multiply the number of light years by 9.46073 × 10²¹.
µm = ly × 9.46073 × 10²¹
1 ly = 9.46073 × 10²¹ µm · 1 µm = 1.057001 × 10⁻²² ly
Worked example
To convert 5 light years to micrometers: 5 ly × 9.46073 × 10²¹ = 4.730365 × 10²² µm.
