Micrometer (µm). A micrometer (micron) is one millionth of a meter, used for cells, bacteria and fiber thickness.
Chain (ch). A chain is 66 feet (20.1168 m), a surveying unit; 80 chains make one mile.
There are 4.97097 × 10⁻⁸ chains in one micrometer.
Multiply the number of micrometers by 4.97097 × 10⁻⁸. For example, 10 micrometers equal 4.97097 × 10⁻⁷ chains.
One chain equals 20,116,800 micrometers.
4.97097 × 10⁻⁵ chains. Other common values: 100 micrometers = 4.97097 × 10⁻⁶ chains and 10,000 micrometers = 0.000497097 chains.
