Chain (ch). A chain is 66 feet (20.1168 m), a surveying unit; 80 chains make one mile.
Nanometer (nm). A nanometer is one billionth of a meter, used for wavelengths of light and the size of molecules.
There are 20,116,800,000 nanometers in one chain.
Multiply the number of chains by 20,116,800,000. For example, 10 chains equal 201,168,000,000 nanometers.
One nanometer equals 4.97097 × 10⁻¹¹ chains.
241,401,600,000 nanometers. Other common values: 5 chains = 100,584,000,000 nanometers and 100 chains = 2,011,680,000,000 nanometers.
