League (lea). A league was roughly the distance a person can walk in an hour; here it is defined as 3 miles (4,828.032 m).
Fermi (fm). A fermi (femtometer) is 10⁻¹⁵ meters, roughly the size of a proton, used in nuclear physics.
There are 4.82803 × 10¹⁸ fermis in one league.
Multiply the number of leagues by 4.82803 × 10¹⁸. For example, 10 leagues equal 4.82803 × 10¹⁹ fermis.
One fermi equals 2.07124 × 10⁻¹⁹ leagues.
5.79364 × 10¹⁹ fermis. Other common values: 5 leagues = 2.41402 × 10¹⁹ fermis and 100 leagues = 4.82803 × 10²⁰ fermis.
