Chain (ch). A chain is 66 feet (20.1168 m), a surveying unit; 80 chains make one mile.
Nautical mile (NM). A nautical mile is exactly 1,852 meters, based on one minute of latitude, and is used in shipping and aviation.
There are 0.0108622 nautical miles in one chain.
Multiply the number of chains by 0.0108622. For example, 10 chains equal 0.108622 nautical miles.
One nautical mile equals 92.0624 chains.
0.130346 nautical miles. Other common values: 5 chains = 0.054311 nautical miles and 100 chains = 1.08622 nautical miles.
