Light Year to Micrometer (ly to μm)
Convert ly to μm — Length converter
Also written as ly to um.
One light year equals 9.461000e+21 μm, so to convert light years to micrometers you multiply the value by 9.461000e+21. A light year is larger than a micrometer — going the other way, 1 μm = 1.056971e-22 ly. For example, 10 ly = 9.461000e+22 μm and 50 ly = 4.730500e+23 μm.
