How to Convert femtometer to light year
1 femtometer [fm] = 1.057000834E-31 light year [ly]
1 light year [ly] = 9.460730472E+30 femtometer [fm]
we use cross multiplication method
femtometer [fm] → light year [ly]
1 → 1.057000834E-31
1.5 → ?( suppose x)
=>1.5*1.057000834E-31=1*x
by simplifying
x=1.585501251E-31
