How to Convert astronomical unit to light year
1 astronomical unit [AU, UA] = 0.0000158125 light year [ly]
1 light year [ly] = 63241.077088 astronomical unit [AU, UA]
we use cross multiplication method
astronomical unit [AU, UA] → light year [ly]
1 → 0.0000158125
1.5 → ?( suppose x)
=>1.5*0.0000158125=1*x
by simplifying
x=0.0000237188
