Chain (ch). A chain is 66 feet (20.1168 m), a surveying unit; 80 chains make one mile.
Micrometer (µm). A micrometer (micron) is one millionth of a meter, used for cells, bacteria and fiber thickness.
There are 20,116,800 micrometers in one chain.
Multiply the number of chains by 20,116,800. For example, 10 chains equal 201,168,000 micrometers.
One micrometer equals 4.97097 × 10⁻⁸ chains.
241,401,600 micrometers. Other common values: 5 chains = 100,584,000 micrometers and 100 chains = 2,011,680,000 micrometers.
