How to convert fermis to light years

1 fermi is equal to 1.057000834 × 10⁻³¹ light years, and 1 light year is equal to 9.460730473 × 10³⁰ fermis. To convert, multiply by the conversion factor:

light years = fermis × 1.057000834 × 10⁻³¹
light years = fermis ÷ 9.460730473 × 10³⁰

Example: convert 1 fm to ly: 1 × 1.057000834 × 10⁻³¹ = 1.057000834 × 10⁻³¹ ly.

About the fermi

The fermi is the traditional name in nuclear physics for the femtometer (10⁻¹⁵ m), named after physicist Enrico Fermi.

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.

Symbol: ly · 1 ly = 9.460730473 × 10¹⁵ m · Category: Astronomical
