Chain (ch). A chain is 66 feet (20.1168 m), a surveying unit; 80 chains make one mile.
Millimeter (mm). A millimeter is one thousandth of a meter, used for small measurements such as thickness and rainfall.
There are 20,116.8 millimeters in one chain.
Multiply the number of chains by 20,116.8. For example, 10 chains equal 201,168 millimeters.
One millimeter equals 4.97097 × 10⁻⁵ chains.
241,402 millimeters. Other common values: 5 chains = 100,584 millimeters and 100 chains = 2,011,680 millimeters.
