To convert fermis to light years, multiply the value by 1.057 × 10⁻³¹. To go the other way, multiply light years by 9.46073 × 10³⁰ to get fermis.

| 1,000 fm | 1.057 × 10⁻²⁸ ly |
| 2,500 fm | 2.6425 × 10⁻²⁸ ly |
| 5,000 fm | 5.285 × 10⁻²⁸ ly |
| 10,000 fm | 1.057 × 10⁻²⁷ ly |
| 100,000 fm | 1.057 × 10⁻²⁶ ly |
| 1,000,000 fm | 1.057 × 10⁻²⁵ ly |
Fermi (fm). A fermi (femtometer) is 10⁻¹⁵ meters, roughly the size of a proton, used in nuclear physics.
Light year (ly). A light year is the distance light travels in one year, about 9.46 trillion kilometers.
There are 1.057 × 10⁻³¹ light years in one fermi.
Multiply the number of fermis by 1.057 × 10⁻³¹. For example, 10 fermis equal 1.057 × 10⁻³⁰ light years.
One light year equals 9.46073 × 10³⁰ fermis.
1.057 × 10⁻²⁸ light years. Other common values: 100 fermis = 1.057 × 10⁻²⁹ light years and 10,000 fermis = 1.057 × 10⁻²⁷ light years.
