Forum rules
Dear convert-me.com forum visitors,
Our forum has been available for many years. In September 2014 we decided to switch it to read-only mode. Month after month we saw less posts with questions and answers from real people and more spam posts. We were spending more and more resources cleaning the spam until there were less them 1 legitimate message per 100 spam posts. Then we decided it's time to stop.
All the posts in the forum will be available and searchable. We understand there are a lot of useful information and we aren't going to remove anything. As for the new questions, you can always ask them on
convert-me.com FaceBook pageThank you for being with us and sorry for any inconveniences this could caused.

I believe you mean "nautical mile."
The generally accepted international value is 1852 m; that value has been used in the US since 1954, although some nations used it since the 1920s.
The origin is as a term to describe 1 minute of arc on the earth's surface, used in navigation, particularly celestril navigation. Since the earth is not a perfect sphere, that value depends on where you measure. Originally, each major sea-going nation had its own value.
