Find the conversion factor from Light year to Kilometer
1 ly = 9.460730473e+15 m · 1 km = 1,000 m
factor = 9.460730473e+15 ÷ 1,000 = 9,460,730,472,581 km per ly
Multiply by the factor: ly cancels, leaving km
km = ly × (km per ly)
1 ly × 9,460,730,472,581 km per ly = 9,460,730,472,581 km
How it works
1 ly = 9460730472581 km, so km = ly × 9460730472581
