Occasionally you will see a reference to an "Admiralty mile". In the 1800s this was used by England and was 6,080 feet long. Today England uses a new "nautical mile" and it is a bit shorter at 1852 meters exactly, or 6,076.1155 feet long. Q1: Does anyone still use the older, slightly large British nautical mile? Do any parts of England still refer to it? Q2: Why was the change made? Was it part of the move to metric in the 1970s? I know that the distance of a nautical mile was originally to be 1/10,000,000th of the distance from the equator to the poles but early estimates of this distance were out a bit. Was this an influence on the adoption of a "new" nautical mile?
