How to Convert kilometer to light year
1 kilometer [km] = 1.057000834E-13 light year [ly]
1 light year [ly] = 9460730472580 kilometer [km]
we use cross multiplication method
kilometer [km] → light year [ly]
1 → 1.057000834E-13
1.5 → ?( suppose x)
=>1.5*1.057000834E-13=1*x
by simplifying
x=1.585501251E-13
