Light year (ly). A light year is the distance light travels in one year, about 9.46 trillion kilometers.
Fermi (fm). A fermi (femtometer) is 10⁻¹⁵ meters, roughly the size of a proton, used in nuclear physics.
There are 9.46073 × 10³⁰ fermis in one light year.
Multiply the number of light years by 9.46073 × 10³⁰. For example, 10 light years equal 9.46073 × 10³¹ fermis.
One fermi equals 1.057 × 10⁻³¹ light years.
1.13529 × 10³² fermis. Other common values: 5 light years = 4.73037 × 10³¹ fermis and 100 light years = 9.46073 × 10³² fermis.
