Chain (ch). A chain is 66 feet (20.1168 m), a surveying unit; 80 chains make one mile.
Fermi (fm). A fermi (femtometer) is 10⁻¹⁵ meters, roughly the size of a proton, used in nuclear physics.
There are 2.01168 × 10¹⁶ fermis in one chain.
Multiply the number of chains by 2.01168 × 10¹⁶. For example, 10 chains equal 2.01168 × 10¹⁷ fermis.
One fermi equals 4.97097 × 10⁻¹⁷ chains.
2.41402 × 10¹⁷ fermis. Other common values: 5 chains = 1.00584 × 10¹⁷ fermis and 100 chains = 2.01168 × 10¹⁸ fermis.
