How to convert femtometers to light years
1 femtometer is equal to 1.057000834 × 10⁻³¹ light years, and 1 light year is equal to 9.460730473 × 10³⁰ femtometers. To convert, multiply by the conversion factor:
light years = femtometers × 1.057000834 × 10⁻³¹
light years = femtometers ÷ 9.460730473 × 10³⁰Example: convert 1 fm to ly: 1 × 1.057000834 × 10⁻³¹ = 1.057000834 × 10⁻³¹ ly.

About the femtometer
A femtometer is 10⁻¹⁵ meters, the scale of atomic nuclei. A proton has a radius of about 0.84 fm.
Symbol: fm · 1 fm = 1 × 10⁻¹⁵ m · Category: Metric (SI)
About the light year
A light-year is the distance light travels in a vacuum in one Julian year (365.25 days): about 9.46 trillion km. The nearest star system, Alpha Centauri, is about 4.37 light-years away.
